This doesn't actually change the external interfaces, so they are still
thread-unsafe, but it makes the code internally pass a pointer to a
local 'struct cache_def' around, so that the core code can be made
thread-safe.

The threaded index preloading will want to verify that the paths leading
up to a pathname are all real directories.

If we have an up-to-date index entry for a file in that directory, we
can know that the directories leading up to that file must be
directories.  No need to do an lstat() on the directory.

Most of the users of "read_directory()" actually want a much simpler
interface than the whole complex (but rather powerful) one.

In fact 'git add' had already largely abstracted out the core interface
issues into a private "fill_directory()" function that was largely
applicable almost as-is to a number of callers.  Yes, 'git add' wants to
do some extra work of its own, specific to the add semantics, but we can
easily split that out, and use the core as a generic function.

This function does exactly that, and now that much simplified
'fill_directory()' function can be shared with a number of callers,
while also ensuring that the rather more complex calling conventions of
read_directory() are used by fewer call-sites.

This also makes the 'common_prefix()' helper function private to dir.c,
since all callers are now in that file.

Commit 00652369 (bash completion: complete variable names for "git
config" with options 2009-05-08) implemented its config variable search
wrong. When a config contains a value with a space and a period (.) in
it, completion erroneously thinks that line in the configuration is
multiple config variables.

For example

 $ cat .git/config
   format.cc = Junio C Hamano <gitster@pobox.com>

 $ git config --unset <TAB>
   format.cc
   <gitster@pobox.com>

Instead of using a for loop splitting across spaces, pipe each line to a
while read loop and beef up the case statement to match only
'config.variable=value'.

Earlier 476cc724 (request-pull: really disable pager, 2009-06-30)
tried to use the correct environment variable to disable paging
from multiple calls to "git log" and friends, but there was one
extra call to "git log" that was not covered by the trick.

Move the setting and exporting of GIT_PAGER much earlier in the

When creating a new argv array from a configured alias and the supplied
command line arguments, the new argv was allocated with one element too
many.  Since the first element of the original argv array is skipped when
copying it to the new_argv, the number of elements that are allocated
should be reduced by one.  'count' is the number of elements that new_argv
contains, and *argcp is the number of elements in the original argv array.
So the total allocation (including the terminating NULL entry) for the
new_argv array should be:

  count + (*argcp - 1) + 1

Also, the explicit assignment of the NULL terminating entry can be avoided
by just copying it over from the original argv array.

The following invocations did not work as expected on Windows:

    git mv foo\bar dest
    git mv foo\ dest

The first command was interpreted as

    git mv foo/bar dest/foo/bar

because the Windows style directory separator was not obeyed when the
basename of 'foo\bar' was computed.

The second command failed because the Windows style directory separator was
not removed from the source directory, whereupon the lookup of the
directory in the index failed.

This fixes both issues by using is_dir_sep() and basename().

I do various statistics on git, and one of the things I look at is merges,
because they are often interesting events to count ("how many merges vs
how much 'real development'" kind of statistics). And you can do it with
some fairly straightforward scripting, ie

	git rev-list --parents HEAD |
		grep ' .* ' |
		git diff-tree --always -s --pretty=oneline --stdin |
		less -S

will do it.

But I finally got irritated with the fact that we can skip merges with
'--no-merges', but we can't do the trivial reverse operation.

So this just adds a '--merges' flag that _only_ shows merges. Now you can
do the above with just a

	git log --merges --pretty=oneline

which is a lot simpler. It also means that we automatically get a lot of
statistics for free, eg

	git shortlog -ns --merges

does exactly what you'd want it to do.
