git-merge-recursive wants an null tree as the fake merge base
while producing the merge result tree. The null tree does not
have to be written out in the object store as it won't be part
of the result, and it is a prime example for using the new
pretend_sha1_file() function.
git-blame needs to register an arbitrary data to in-core index
while annotating a working tree file (or standard input), but
git-blame is a read-only application and the user of it could
even lack the privilege to write into the object store; it is
another good example for pretend_sha1_file().

Warning: this changes the semantics.
This makes "git blame" without any positive rev to start digging
from the working tree copy, which is made into a fake commit
whose sole parent is the HEAD.
It also adds --contents <file> option to pretend as if the
working tree copy has the contents of the named file. You can
use '-' to make the command read from the standard input.
If you want the command to start annotating from the HEAD
commit, you need to explicitly give HEAD parameter.

Starting a pager defeats the purpose of the incremental output
mode. This changes git-blame to only paginate if --incremental
was not given.
git -p blame --incremental still starts the pager, though.

Otherwise a pathname that has funny characters such as LF would
screw up the parsing programs of the output.
Strictly speaking, this is not backward compatible, but the
current output for pathnames that have embedded LF and such
cannot be sanely parsed anyway, and pathnames that only use
characters from the portable pathname character set won't be
affected.

This adds --incremental option to help GUI porcelains to show
the result from git-blame incrementally. The output gives the
origin information in the same format as the porcelain format.
The first line has commit object name, the line number of the
first line in the group in the original file, the line number of
that file in the final image, and number of lines in the group.
Then subsequent lines show the metainformation for the commit
when the commit is shown for the first time, except the filename
information is always shown (we cannot even make it conditional
to -C option as blame always follows the renaming of the file
wholesale).

This is a mechanical clean-up of the way *.c files include
system header files.
(1) sources under compat/, platform sha-1 implementations, and
xdelta code are exempt from the following rules;
(2) the first #include must be "git-compat-util.h" or one of
our own header file that includes it first (e.g. config.h,
builtin.h, pkt-line.h);
(3) system headers that are included in "git-compat-util.h"
need not be included in individual C source files.
(4) "git-compat-util.h" does not have to include subsystem
specific header files (e.g. expat.h).

When blame.blankboundary is set (or -b option is given), commit
object names are blanked out in the "human readable" output
format for boundary commits.
When blame.showroot is not set (or --root is not given), the
root commits are treated as boundary commits. The code still
attributes the lines to them, but with -b their object names are
not shown.

When blaming with revision ranges, often many lines are attributed
to different commits at the boundary, but they are not interesting
for the purpose of finding project history during that revision range.
This outputs the lines blamed on boundary commits differently. When
showing "human format" output, their SHA-1 are shown with '^' prefixed.
In "porcelain format", the commit will be shown with an extra attribute
line "boundary".

We lacked "--" termination in the underlying init_revisions() call
which made it impossible to specify a revision that happens to
have the same name as an existing file.

We used to get the case that more than two paths came from the
same commit wrong when computing the output width and deciding
to turn on --show-name option automatically. When we find that
lines that came from a path that is different from what we
started digging from, we should always turn --show-name on, and
we should count the name length for all files involved.

The graft file can contain comment lines and read_graft_line can
return NULL for such an input, which should be skipped by the
reader.

Just make it take over blame's place. Documentation and command
have all stopped mentioning "git-pickaxe". The built-in synonym
is left in the command table, so you can still say "git pickaxe",
but it probably is a good idea to retire it as well.
