Fix setup_git_directory_gently() with relative GIT_DIR & GIT_WORK_TREE

There are a few programs, such as config and diff, which allow running
without a git repository.  Therefore, they have to call
setup_git_directory_gently().

However, when GIT_DIR and GIT_WORK_TREE were set, and the current
directory was a subdirectory of the work tree,
setup_git_directory_gently() would return a bogus NULL prefix.

Fix embarrassing "git log --follow" bug

generation", commit b7bb760d5ed4881422673d32f869d140221d3564).

Why? Because --follow obviously requires the diff machinery to function,
exactly the same way pickaxe does.

So everybody is away right now, but considering that nobody even noticed
this bug, I don't think it matters. But for the record, here's the trivial
one-liner fix (well, two, since I also fixed the comment).

Because of the nature of the bug, if you ask for patches when following
(which is one of the things I normally do), the bug is hidden, because
then the request for diff output will automatically also enable the diffs
themselves.

So while "git log --follow <filename>" didn't work, adding a "-p"
magically made it work again even without this fix.

diffcore-rename: cache file deltas

We find rename candidates by computing a fingerprint hash of

inherently O(n^2) comparisons, so it pays in CPU time to
hoist the (rather expensive) computation of the fingerprint
out of that loop (or to cache it once we have computed it once).

Previously, we didn't keep the filespec information around
because then we had the potential to consume a great deal of
memory. However, instead of keeping all of the filespec
data, we can instead just keep the fingerprint.

estimate_similarity not to needlessly repopulate the
filespec data when we already have the hash.

Fix revision log diff setup, avoid unnecessary diff generation

We used to incorrectly start calculating diffs whenever any argument but
'-z' was recognized by the diff options parsing. That was bogus, since not
all arguments result in diffs being needed, so we just waste a lot of time
and effort on calculating diffs that don't matter.

This actually also fixes another bug in "git log". Try this:

git log -C

and notice how it prints an extra empty line in between log entries, even
though it never prints the actual diff (because we didn't ask for any diff
format, so the diff machinery never prints anything).

With this patch, that bogus empty line is gone, because "revs->diff" is
never set.  So this isn't just a "wasted time and effort" issue, it's also
a slight semantic fix.

When making a partial commit, git-commit uses git-ls-files with
the --error-unmatch option to expand and sanity check the user
supplied path patterns.  When any path pattern does not match
with the paths known to the index, it errors out, in order to
catch a common mistake to say "git commit Makefiel cache.h"

misspelled "Makefile").  This detection however does not work
well when the path has already been removed from the index.

If you drop a path from the index and try to commit that
partially, i.e.

$ git rm COPYING
$ git commit -m 'Remove COPYING' COPYING

the command complains because git does not know anything about
COPYING anymore.

This introduces a new option --with-tree to git-ls-files and
uses it in git-commit when we build a temporary index to
write a tree object for the partial commit.

send-email: make message-id generation a bit more robust

Earlier code took Unix time and appended a few random digits.
If you are firing off many messages within a second, you could
issue the same id to different messages, which is a no-no.  If
you send out 31 messages within a single second, with random
integer taken out of rand(4200), you have about 10% chance of
producing the same message ID.

This fixes the problem by uses a prefix string which is
constant-per-invocation (time and pid), with a serial number for
each message generated by the process appended at the end.

git-gui: Disable native platform text selection in "lists"

Sometimes we use a Tk text widget as though it were a listbox.
This happens typically when we want to show an icon to the left
of the text label or just when a text widget is generally a better
choice then the native listbox widget.

In these cases if we want the user to have control over the selection
we implement our own "in_sel" tag that shows the selected region
and we perform our own selection management in the background
via keybindings and mouse bindings.  In such uses we don't want
the user to be able to activate the native platform selection by
dragging their mouse through the text widget.  Doing so creates a
very confusing display and the user is left wondering what it may
mean to have two different types of selection in the same widget.

Tk doesn't allow us to delete the "sel" tag that it uses internally
to manage the native selection but it will allow us to make it
invisible by setting the tag to have the same display properties
as unselected text.  So long as we don't actually use the "sel"
tag for anything in code its effectively invisible.

Split grep arguments in a way that does not requires to add /dev/null.

In order to (almost) always show the name of the file without
relying on "-H" option of GNU grep, we used to add /dev/null to
the argument list unless we are doing -l or -L.  This caused
"/dev/null:0" to show up when -c is given in the output.

It is not enough to add -c to the set of options we do not pass
/dev/null for.  When we have too many files, we invoke grep
multiple times and we need to avoid giving a widow filename to
the last invocation -- otherwise we will not see the name.

This keeps two filenames when the argv[] buffer is about to
overflow and we have not finished iterating over the index, so
that the last round will always have at least two paths to work
with (and not require /dev/null).

An obvious and the only exception is when there is only 1 file
that is given to the underlying grep, and in that case we avoid
passing /dev/null and let the external "grep -c" report only the
number of matches.
