dff4b0ef30 am: format is in $patch_format, not parse_patch
The error message given when the patch format was not recognized was
wrong, since the variable checked was $parse_patch rather than
$patch_format. Fix by checking the non-emptyness of the correct
variable.

2a6f08ac1f am: refresh the index at start and --resolved
If a file is unchanged but stat-dirty, we may erroneously
fail to apply patches, thinking that they conflict with a
dirty working tree.

This patch adds a call to "update-index --refresh". It comes
as late as possible, so that we don't bother with it for
thinks like "git rebase --abort", or when mbox-splitting
fails. However, it does come before we actually start
applying patches, meaning we will only call it once when we
start applying patches (or any time we return to "am" after
having resolved conflicts), and not once per patch.

0e8341f29d am: ignore leading whitespace before patch
Some web-based email clients prepend whitespace to raw message
transcripts to workaround content-sniffing in some browsers.  Adjust
the patch format detection logic to ignore leading whitespace.

So now you can apply patches from GMail with "git am" in three steps:

 1. choose "show original"
 2. tell the browser to "save as" (for example by pressing Ctrl+S)
 3. run "git am" on the saved file

This fixes a regression introduced by v1.6.4-rc0~15^2~2 (git-am
foreign patch support: autodetect some patch formats, 2009-05-27).
GMail support was first introduced to "git am" by v1.5.4-rc0~274^2
(Make mailsplit and mailinfo strip whitespace from the start of the
input, 2007-11-01).

43c23251f9 am: use get_author_ident_from_commit instead of mailinfo when rebasing
In certain situations, commit authorship can consist of an invalid
e-mail address. For example, this is the case when working with git svn
repos where the author email has had the svn repo UUID appended such as:

 author@example.com <author@example.com@deadbeef-dead-beef-dead-beefdeadbeef>

Given such an address, mailinfo extracts the authorship incorrectly as
it assumes a valid domain. However, when rebasing the original
authorship should be preserved irrespective of its validity as an email
address.

Using get_author_ident_from_commit instead of mailinfo when rebasing
preserves the original authorship.

05bdcfe5fc git-am: suggest what to do with superfluous patches
Particularly in the context of rebase, conflicts frequently occur
because the change in the patch to be applied was made obsolete by new
upstream commits. In this case, solving the conflict effectively means
skipping the patch. However, it's not always readily apparent that the
patch needs to be skipped, and when people solve the conflict and try
git rebase --continue, they get confronted with a message of

  No changes - did you forget to use 'git add'?

That's not very helpful if you did actually stage your changes and they
happen to turn the patch into a no-op. This extends the message to point
out what's going on.

0ba17dd022 am -3: recover the diagnostic messages for corrupt patches
"git am -3" first tries to apply the patch without any extra trick, and
applies it to a synthesized tree for 3-way merge after the first attempt
fails.  "git apply" exits with status 1 for a patch that is well-formed
but is not applicable (and it dies on other errors with non-zereo, non-1
status) and has an optimization to fall back to the 3-way merge only in
the case.

An earlier patch 3ddd170 (am: suppress apply errors when using 3-way,
2009-06-16) squelched diagnostic messages from the first attempt, not to
be shown to the end user.  This worked reasonably well if the reason the
first application failed was because the patch was made against a wrong
version.

When the patch is corrupt (e.g. line-wrapped or leading whitespaces got
dropped), however, because the second patch application is not even
attempted, the error message from the first application is never shown
and is forever lost.  This message is necessary to locate where the patch
is corrupt and fix it up.

We could fix this issue by reverting 3dd170, or keeping the error message
to somewhere and showing it, but because this is an error codepath, the
easiest is to disable the optimization.  The second patch application is
attempted even when the input is corrupt, and it will notice, diagnose,
and stop with an error message.

We have to deal with two separate code paths: a normal rebase, which
actually goes through git-am; and rebase {-m|-s}.

The only small issue with both is that they need to remember the
original sha1 across a possible conflict resolution.  rebase -m
already puts this information in $dotest/current, and we just
introduce a similar file for git-am.

Note that in git-am, the hook really only runs when coming from
git-rebase: the code path that sets the $dotest/original-commit file
is guarded by a test for $dotest/rebasing.

line-endings, 2009-08-04) fixed "git mailsplit" to help people with
MUA whose output from save-as command uses CRLF as line terminators by
stripping CR at the end of lines.

However, when you know you are feeding output from "git format-patch"
directly to "git am", and especially when your contents have CR at the
end of line, such stripping is undesirable.  To help such a use case,
teach --keep-cr option to "git am" and pass that to "git mailinfo".

f6dff119d5 am: Fix launching of pager
The pagination functionality in git am has some problems:

 - It does not check if stdout is a tty, so it always paginates.

 - If $GIT_PAGER uses any environment variables, they are being
   ignored, since it does not run $GIT_PAGER through eval.

 - If $GIT_PAGER is set to the empty string, instead of passing
   output through to stdout, it tries to run $dotest/patch.

Fix them.  While at it, move the definition of git_pager() to
git-sh-setup so authors of other commands are not tempted to
reimplement it with the same mistakes.

and ensure that they look like header fields. The headers are always
separated from the message body with a blank line. When Thunderbird saves
the message the blank line separating the headers from the body includes a
CR. The patch detection is failing because a CRLF doesn't match /^$/. Fix
this by allowing a CR to exist on the separating line.

c970a6fd01 Remove dead code from "git am"
Ever since the initial implementation, "git am" had kept a dead code that
never triggered due to a typo in the variable name.  Worse yet, the code,
if it weren't for the typo, would have attempted to add "[PATCH] " at the
beginning of the Subject: header when "git am" is run with its "-k"
option.  However, because "git am -k" tells mailinfo to keep such prefix
when parsing the input, the "[PATCH] " added by this dead code would have
really been unnecessary duplicate.

Embarrassing is that we kept _maintaining_ the codepath without anybody
noticing for four years.

e1622bfcba Protect scripted Porcelains from GREP_OPTIONS insanity
If the user has exported the GREP_OPTIONS environment variable, the output
from "grep" and "egrep" in scripted Porcelains may be different from what
they expect.  For example, we may want to count number of matching lines,
by "grep" piped to "wc -l", and GREP_OPTIONS=-C3 will break such use.

The approach taken by this change to address this issue is to protect only
our own use of grep/egrep.  Because we do not unset it at the beginning of
our scripts, hook scripts run from the scripted Porcelains are exposed to
the same insanity this environment variable causes when grep/egrep is used
to implement logic (e.g. "grep | wc -l"), and it is entirely up to the
hook scripts to protect themselves.

On the other hand, applypatch-msg hook may want to show offending words in
the proposed commit log message using grep to the end user, and the user
might want to set GREP_OPTIONS=--color to paint the match more visibly.
The approach to protect only our own use without unsetting the environment
variable globally will allow this use case.

0fcb2caf29 am: allow individual e-mail files as input
We traditionally allowed a mbox file or a directory name of a maildir (but
never an individual file inside a maildir) to be given to "git am".  Even
though an individual file in a maildir (or more generally, a piece of
RFC2822 e-mail) is not a mbox file, it contains enough information to
create a commit out of it, so there is no reason to reject one.  Running
mailsplit on such a file feels stupid, but it does not hurt.

This builds on top of a5a6755 (git-am foreign patch support: introduce
patch_format, 2009-05-27) that introduced mailbox format detection.  The
codepath to deal with a mbox requires it to begin with "From " line and
also allows it to begin with "From: ", but a random piece of e-mail can
and often do begin with any valid RFC2822 header lines.

Instead of checking the first line, we extract all the lines up to the
first empty line, and make sure they look like e-mail headers.

A test is added to t4150 to demonstrate this feature.

c2ca1d79db Allow mailsplit (and hence git-am) to handle mails with CRLF line-endings
It is not that uncommon to have mails with DOS line-ending, notably
Thunderbird and web mailers like Gmail (when saving what they call
"original" message).  So modify mailsplit to convert CRLF line-endings to
just LF.

Since git-rebase is built on top of git-am, add an option to mailsplit to
be used by git-am when it is acting on behalf of git-rebase, to refrain
from doing this conversion.

And add a test to make sure that rebase still works.
