0af88c15e2 grep -O: allow optional argument specifying the pager (or editor)
Suppose you want to edit all files that contain a specific search term.
Of course, you can do something totally trivial such as

	git grep -z -e <term> | xargs -0r vi +/<term>

but maybe you are happy that the same will be achieved by

	git grep -Ovi <term>

now.

678e484b7d grep: Add the option '--open-files-in-pager'
This adds an option to open the matching files in the pager, and if the
pager happens to be "less" (or "vi") and there is only one grep pattern,
it also jumps to the first match right away.

The short option was chose as '-O' to avoid clashes with GNU grep's
options (as suggested by Junio).

So, 'git grep -O abc' is a short form for 'less +/abc $(grep -l abc)'
except that it works also with spaces in file names, and it does not
start the pager if there was no matching file.

[jn: rebased and added tests; with error handling fix from Junio
squashed in]

685359cf2d Unify code paths of threaded greps
There were three awfully similar code paths ending the threaded grep. It
is better to avoid duplicated code, though.

This change might very well prevent a race, where the grep patterns were

30d00c395e grep: refactor grep_objects loop into its own function
Simplify cmd_grep by splitting off the loop that finds matches in a
list of trees.  So now the main part of cmd_grep looks like:

	if (!use_index) {
		int hit = grep_directory(&opt, paths);
		if (use_threads)
			hit |= wait_all();
		return !hit;
	}
	if (!list.nr) {
		if (!cached)
			setup_work_tree();
		int hit = grep_cache(&opt, paths, cached);
		if (use_threads)
			hit |= wait_all;
		return !hit;
	}
	hit = grep_objects(&opt, path, &list);
	if (use_threads)
		hit |= wait_all();
	return !hit;

and is ripe for further refactoring.

f69c501832 rev-list: introduce --count option
Add a --count option that, instead of actually listing the commits,
merely counts them.

This is mostly geared towards script use, and to this end it acts
specially when used with --left-right: it outputs the left and right
counts separately.  Previously, scripts would have to run a shell loop
or small inline script over to achieve the same.  (Without
--left-right, a simple |wc -l does the job.)

157aaea5ff log_ref_setup: don't return stack-allocated array
859c301 (refs: split log_ref_write logic into log_ref_setup,
2010-05-21) refactors the stack allocation of the log_file array into
the new log_ref_setup() function, but passes it back to the caller.

Since the original intent seems to have been to split the work between
log_ref_setup and log_ref_write, make it the caller's responsibility
to allocate the buffer.

1a4b986c32 send-email: handle Windows paths for display just like we do for processing
In git-send-email.perl, here are two checks to determine if
$smtp_server is an absolute path (so it'll be treated as a mailer) or
not (so it'll be treated as a hostname).  The one that handles actual
mail processing has been taught to recognize Windows pathnames by
commit 33b2e81f.

The other check is just to tell the user what happened, so it's far
less important, but the current state is that we will still claim to
the user that c:/foo/bar is a server. =)  This makes the second check
consistent with the first.

If the stdout of the command is connected to a terminal but the stderr
has been redirected, the odds are good that the user can't see any
question we print out to stderr.  This will result in a "mysterious
hang" while the app is waiting for user input.

It seems better to be conservative, and avoid asking for input
whenever the stderr is not a terminal, just like we do for stdin.

495281174b Add a few more values for receive.denyCurrentBranch
For a long time, this developer thought that Git's insistence that
pushing into the current branch is evil was completely merited.

Just for fun, the original patch tried to show people that Git is right
there, and that it causes more trouble than it does good when Git allows
you to try to update the working tree for fast-forwards, or to detach the
HEAD, depending on some config settings.

Surprisingly, the opposite was shown.

So here is the support for two new options you can give the config
variable receive.denyCurrentBranch:

'updateInstead':
	Try to merge the working tree with the new tip of the branch
	(which can lead to really horrible merge conflicts).

'detachInstead':
	Detach the HEAD, thereby avoiding a disagreement between the
	HEAD and the index (as well as the working tree), possibly
	leaving the local user wondering how on earth her HEAD became
	so detached.

be8fa18ce3 fix mingw stat() and lstat() implementations for handling symlinks
In msysGit the stat() function has been implemented using mingw_lstat
which sets the st_mode member to S_IFLNK when a symbolic links is found.
This causes the is_executable function to return when git attempts to
build a list of available commands in the help code and we end up missing
most git commands. (msysGit issue #445)

This patch modifies the implementation so that lstat() will return the link
flag but if we are called as stat() we read the size of the target and set
the mode to that of a regular file.

2d2cd7a2f7 gitk: work around ridiculous command line restriction on Windows
On Windows, there are dramatic problems when a command line grows
beyond PATH_MAX, which is restricted to 8191 characters on XP and
later (according to http://support.microsoft.com/kb/830473).

Work around this by just cutting off the command line at that length
(actually, at a space boundary) in the hope that only negative
refs are chucked: gitk will then do unnecessary work, but that is
still better than flashing the gitk window and exiting with exit
status 5 (which no Windows user is able to make sense of).

This fixes msysGit issue 387.

2397cec9e6 git-gui: Avoid using the <<Copy>> binding as a menu accelerator on win32
On Windows the Control-C binding is used to copy and is mapped to the Tk
virtual event <<Copy>>. In the initial git-gui dialog this is also bound
as an accelerator for the Clone menu item. The effect is that both bindings
run, copying the text but resetting the clone page or switching to the clone
page when the user tries to copy text from one of the entry fields.
This patch avoids this by using Control-L instead for Windows only.

488606f88f mingw: make failures to unlink or move raise a question
On Windows in case a program is accessing a file unlink or
move operations may fail. To give the user a chance to correct
this we simply wait until the user asks us to retry or fail.

This is useful because of the following use case which seem
to happen rarely but when it does it is a mess:

After making some changes the user realizes that he was on the
incorrect branch. When trying to change the branch some file
is still in use by some other process and git stops in the
middle of changing branches. Now the user has lots of files
with changes mixed with his own. This is especially confusing
on repositories that contain lots of files.

Although the recent implementation of automatic retry makes
this scenario much more unlikely lets provide a fallback as
a last resort.
