For this purpose the path lookup is done manually, and the found file
is inspected for the interpreter. If one is found, the script is spawned
under the interpreter; otherwise, the program is spawned normally.
Windows does not have fork(), but something called spawn() that is roughly
equivalent to a fork()/exec() pair, factor out the Unix style code into
a function that does it more similarly to spawn(). Now the Windows style
spawn() can more easily be employed to achieve the same that the Unix style
code does.
Windows does not return EISDIR when a directory is opened as file.
These instances are detected by checking explicitly whether the offending
file is indeed a directory, and then the errno value is adjusted accordingly.
When an external git command is invoked, it can be a Bourne shell script.
This patch looks into the command file to see whether it is one.
In this case, the command line is rearranged to invoke the shell
with the proper arguments.
Moreover, the arguments are quoted if necessary because Windows'
spawn functions paste the arguments again into a command line that
is disassembled by the invoked process.
An earlier patch has implemented getcwd() so that it converts the
drive letter into the POSIX-like path that is used internally by
MinGW (C:\foo => /c/foo), but this style does not work outside
the MinGW shell. It is better to just convert the backslashes
to forward slashes and handle the drive letter explicitly.
Perl is just used to reverse stdin, which can be done with a simple
sed construct as well.

* master:
Documentation: Generate command lists.
Documentation: sync git.txt command list and manual page title
Documentation: move command list in git.txt into separate files.
prune-packed: add -q to usage
Document --ignore-if-in-upstream in git-format-patch
Shell syntax fix in git-reset
Use standard -t option for touch.
Use fixed-size integers for .idx file I/O
Use fixed-size integers for the on-disk pack structure.
git-format-patch: the default suffix is now .patch, not .txt
git-format-patch: make --binary on by default
Add --summary to git-format-patch by default
git-format-patch -3
Document pack .idx file format upgrade strategy.
Refer users to git-rev-parse for revision specification syntax.
Document the master@{n} reflog query syntax.
Documentation/git-parse-remote.txt: we deal with config vars as well
Documentation: m can be relative in "git-blame -Ln,m"
Documentation: suggest corresponding Porcelain-level in plumbing docs.
Documentation/git-resolve: deprecated.
This moves the source of the list of commands and categorization
to the end of Documentation/cmd-list.perl, so that re-categorization
and re-ordering would become easier to manage.

Non-GNU touch do not have the -d option to take free form
date strings. The POSIX -t option should be more widespread.
For this to work, date needs to output YYYYMMDDHHMM.SS date strings.

Plain integer types without a fixed size can vary between platforms. Even
though all common platforms use 32-bit ints, there is no guarantee that
this won't change at some point. Furthermore, specifying an integer type
with explicit size makes the definition of structures more obvious.

Editors often give easier handling of patch files if the
filename ends with .patch, so use it instead of .txt.

It does not make much sense to generate a patch that cannot be
applied. If --text is specified on the command line it still
takes precedence.

This adds --summary output in addition to the --stat to the
output from git-format-patch by default.
I think additions, removals and filemode changes are rare but
notable events and always showing it makes sense.

This teaches "git-format-patch" to honor the --max-count
parameter revision traversal machinery takes, so that you can
say "git-format-patch -3" to process the three topmost commits
from the current HEAD (or "git-format-patch -2 topic" to name a
specific branch).

Way back when Junio developed the 64 bit index topic he came up
with a means of changing the .idx file format so that older Git
clients would recognize that they don't understand the file and
refuse to read it, while newer clients could tell the difference
between the old-style and new-style .idx files. Unfortunately
this wasn't recorded anywhere.
This change documents how we might go about changing the .idx
file format by using a special signature in the first four bytes.
Credit (and possible blame) goes completely to Junio for thinking
up this technique.
The change also modifies the error message of the current Git code
so that users get a recommendation to upgrade their Git software
should this version or later encounter a new-style .idx which it
cannot process. We already do this for the .pack files, but since
we usually process the .idx files first its important that these
files are recognized and encourage an upgrade.

The revision specification syntax (sometimes referred to as
SHA1-expressions) is accepted almost everywhere in Git by
almost every tool. Unfortunately it is only documented in
git-rev-parse.txt, and most users don't know to look there.
