Jeff King d85d7ecb80 add--interactive: quote commentChar regex
Since c9d961647 (i18n: add--interactive: mark
edit_hunk_manually message for translation, 2016-12-14),
when the user asks to edit a hunk manually, we respect
core.commentChar in generating the edit instructions.
However, when we then strip out comment lines, we use a
simple regex like:

  /^$commentChar/

If your chosen comment character is a regex metacharacter,
then that will behave in a confusing manner ("$", for
instance, would only eliminate blank lines, not actual
comment lines).

We can fix that by telling perl not to respect
metacharacters.

Jeff King d5addcf522 add--interactive: handle EOF in prompt_yesno
The prompt_yesno function loops indefinitely waiting for a
"y" or "n" response. But it doesn't handle EOF, meaning
that we can end up in an infinite loop of reading EOF from
stdin. One way to simulate that is with:

  echo e | GIT_EDITOR='echo corrupt >' git add -p

Let's break out of the loop and propagate the undef to the
caller. Without modifying the callers that effectively turns
it into a "no" response. This is reasonable for both of the
current callers, and it leaves room for any future caller to
check for undef explicitly.

David Aguilar 0af85f84bd mergetools/meld: improve compatibiilty with Meld on macOS X
The macOS X fork of Meld[1] requires a "=" in the "--output"
argument, as it uses a wrapper[2] script that munges the
"--output" argument before calling into the common "meld"
script.

The macOS X wrapper script[2] accepts "--output=<filename>"
only, despite the fact that the underlying meld code accepts
both "--output <filename" and "--output=<filename>"[3].

All versions of meld which accept "--output" accept it in
the "--output=<filename>" form, so use "--output=<file>" for
maximum compatibility.

Johannes Schindelin a9bcf6586d alias: use the early config machinery to expand aliases
Instead of discovering the .git/ directory, reading the config and then
trying to painstakingly reset all the global state if we did not find a
matching alias, let's use the early config machinery instead.

It may look like unnecessary work to discover the .git/ directory in the
early config machinery and then call setup_git_directory_gently() in the
case of a shell alias, repeating the very same discovery *again*.
However, we have to do this as the early config machinery takes pains
*not* to touch any global state, while shell aliases expect a possibly
changed working directory and at least the GIT_PREFIX and GIT_DIR
variables to be set.

This change also fixes a known issue where Git tried to read the pager
config from an incorrect path in a subdirectory of a Git worktree if an
alias expanded to a shell command.

Johannes Schindelin 3f9c5dfb71 t7006: demonstrate a problem with aliases in subdirectories
When expanding aliases, the git_dir is set during the alias expansion
(by virtue of running setup_git_directory_gently()).

This git_dir may be relative to the current working directory, and
indeed often is simply ".git/".

When the alias expands to a shell command, we restore the original
working directory, though, yet we do not reset git_dir.

As a consequence, subsequent read_early_config() runs will mistake the
git_dir to be populated properly and not find the correct config.

Demonstrate this problem by adding a test case.

Johannes Schindelin 659fef199f help: use early config when autocorrecting aliases
Git has this feature which suggests similar commands (including aliases)
in case the user specified an unknown command.

This feature currently relies on a side effect of the way we expand
aliases right now: when a command is not a builtin, we use the regular
config machinery (meaning: discovering the .git/ directory and
initializing global state such as the config cache) to see whether the
command refers to an alias.

However, we will change the way aliases are expanded in the next
commits, to use the early config instead. That means that the
autocorrect feature can no longer discover the available aliases by
looking at the config cache (because it has not yet been initialized).

So let's just use the early config machinery instead.

This is slightly less performant than the previous way, as the early
config is used *twice*: once to see whether the command refers to an
alias, and then to see what aliases are most similar. However, this is
hardly a performance-critical code path, so performance is less important
here.

Johannes Schindelin e2e1425107 config: report correct line number upon error
When get_value() parses a key/value pair, it is possible that the line
number is decreased (because the \n has been consumed already) before the
key/value pair is passed to the callback function, to allow for the
correct line to be attributed in case of an error.

However, when git_parse_source() asks get_value() to parse the key/value
pair, the error reporting is performed *after* get_value() returns.

Which means that we have to be careful not to increase the line number
in get_value() after the callback function returned an error.

Johannes Schindelin 69743f9b4f discover_git_directory(): avoid setting invalid git_dir
When discovering a .git/ directory, we take pains to ensure that its
repository format version matches Git's expectations, and we return NULL
otherwise.

However, we still appended the invalid path to the strbuf passed as
argument.

Let's just reset the strbuf to the state before we appended the .git/
directory that was eventually rejected.

There is another early return path in that function, when
setup_git_directory_gently_1() returns GIT_DIR_NONE or an error. In that
case, the gitdir parameter has not been touched, therefore there is no
need for an equivalent change in that code path.

Jeff King 0c977dbc81 diff-highlight: split code into module
The diff-so-fancy project is also written in perl, and most
of its users pipe diffs through both diff-highlight and
diff-so-fancy. It would be nice if this could be done in a
single script. So let's pull most of diff-highlight's code
into its own module which can be used by diff-so-fancy.

In addition, we'll abstract a few basic items like reading
from stdio so that a script using the module can do more
processing before or after diff-highlight handles the lines.
See the README update for more details.

One small downside is that the diff-highlight script must
now be built using the Makefile. There are ways around this,
but it quickly gets into perl arcana. Let's go with the
simple solution. As a bonus, our Makefile now respects the
PERL_PATH variable if it is set.

Andreas Heiduk 773a88914f doc: do not use rm .git/index when normalizing line endings
When illustrating how to normalize the line endings, the
documentation in gitattributes tells the user to `rm .git/index`.

This is incorrect for two reasons:

 - Users shouldn't be instructed to mess around with the internal
   implementation of Git using raw file system tools like `rm`.

 - Within a submodule or an additional working tree `.git` is just a
   file containing a `gitdir: <path>` pointer into the real `.git`
   directory.  Therefore `rm .git/index` does not work.

The purpose of the `rm .git/index` instruction is to remove all entries
from the index without touching the working tree.  The way to do this
with Git is to use `read-tree --empty`.
