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
free()d before waiting that all threads finished.

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.

ed40a0951c grep: support NUL chars in search strings for -F
Search patterns in a file specified with -f can contain NUL characters.
The current code ignores all characters on a line after a NUL.

Pass the actual length of the line all the way from the pattern file to
fixmatch() and use it for case-sensitive fixed string matching.

431d6e7bc8 grep: enable threading for context line printing
If context lines are to be printed, grep separates them with hunk marks
("--\n").  These marks are printed between matches from different files,
too.  They are not printed before the first file, though.

Threading was disabled when context line printing was enabled because
avoiding to print the mark before the first line was an unsolved
synchronisation problem.  This patch separates the code for printing
hunk marks for the threaded and the unthreaded case, allowing threading
to be turned on together with the common -ABC options.

->show_hunk_mark, which controls printing of hunk marks between files in
show_line(), is now set in grep_buffer_1(), but only if some results
have already been printed and threading is disabled.  The threaded case
is handled in work_done().

81b50f3ce4 Move 'builtin-*' into a 'builtin/' subdirectory
This shrinks the top-level directory a bit, and makes it much more
pleasant to use auto-completion on the thing. Instead of

	[torvalds@nehalem git]$ em buil<tab>
	Display all 180 possibilities? (y or n)
	[torvalds@nehalem git]$ em builtin-sh
	builtin-shortlog.c     builtin-show-branch.c  builtin-show-ref.c
	builtin-shortlog.o     builtin-show-branch.o  builtin-show-ref.o
	[torvalds@nehalem git]$ em builtin-shor<tab>
	builtin-shortlog.c  builtin-shortlog.o
	[torvalds@nehalem git]$ em builtin-shortlog.c

you get

	[torvalds@nehalem git]$ em buil<tab>		[type]
	builtin/   builtin.h
	[torvalds@nehalem git]$ em builtin		[auto-completes to]
	[torvalds@nehalem git]$ em builtin/sh<tab>	[type]
	shortlog.c     shortlog.o     show-branch.c  show-branch.o  show-ref.c     show-ref.o
	[torvalds@nehalem git]$ em builtin/sho		[auto-completes to]
	[torvalds@nehalem git]$ em builtin/shor<tab>	[type]
	shortlog.c  shortlog.o
	[torvalds@nehalem git]$ em builtin/shortlog.c

which doesn't seem all that different, but not having that annoying
break in "Display all 180 possibilities?" is quite a relief.

NOTE! If you do this in a clean tree (no object files etc), or using an
editor that has auto-completion rules that ignores '*.o' files, you
won't see that annoying 'Display all 180 possibilities?' message - it
will just show the choices instead.  I think bash has some cut-off
around 100 choices or something.

So the reason I see this is that I'm using an odd editory, and thus
don't have the rules to cut down on auto-completion.  But you can
simulate that by using 'ls' instead, or something similar.
