just leave the underscore in place.  Using '=20' seems to work better.

Only git-ls-files(1) describes the gitignore format in detail, and it does so
with reference to git-ls-files options.  Most users don't use the plumbing
command git-ls-files directly, and shouldn't have to look in its manpage for
information on the gitignore format.

Create a new manpage gitignore(5) (Documentation/gitignore.txt), and factor
out the gitignore documentation into that file, changing it to refer to
.gitignore and $GIT_DIR/info/exclude as used by porcelain commands.  Reference
gitignore(5) from other relevant manpages and documentation.  Remove
now-redundant information on exclude patterns from git-ls-files(1), leaving
only information on how git-ls-files options specify exclude patterns and what
precedence they have.

Make hexval_table[] "const".  Also make sure that the accessor
function hexval() does not access the table with out-of-range
values by declaring its parameter "unsigned char", instead of
"unsigned int".

With this, gcc can just generate:

	movzbl  (%rdi), %eax
	movsbl  hexval_table(%rax),%edx
	movzbl  1(%rdi), %eax
	movsbl  hexval_table(%rax),%eax
	sall    $4, %edx
	orl     %eax, %edx

Reasonably new versions of the cvs CLI client allow one to
specifiy CVS_SERVER as a method variable directly in
CVSROOT. This is way more convinient than using an
environment variable since it gets saved in CVS/Root.

Since I only discovered this by accident I guess there

Johannes Sixt asked me to try to avoid embedding the runtime location
of git-gui's library directory in the executable script.  Not embedding
it helps the MinGW to be relocatable to another directory should a user
wish to install the programs in a directory other than the location the
packager wanted them to be installed into.

Most of this is a hack.  We try to determine if the path of our master
git-gui script will be able to locate the lib by ../share/git-gui/lib.
This should be true if $(gitexecdir) and $(libdir) have the same prefix.
If they do then we defer the assignment of $(libdir) until runtime, and
we get it from $argv0 rather than embedding it into the script itself.

If the repository contained an expanded ident keyword (i.e. $Id:XXXX$),
then the wrong bytes were discarded, and the Id keyword was not
expanded.  The fault was in convert.c:ident_to_worktree().

Previously, when a "$Id:" was found in the repository version,
ident_to_worktree() would search for the next "$" after this, and
discarded everything it found until then.  That was done with the loop:

    do {
        ch = *cp++;
        if (ch == '$')
            break;
        rem--;
    } while (rem);

The above loop left cp pointing one character _after_ the final "$"
(because of ch = *cp++).  This was different from the non-expanded case,
were cp is left pointing at the "$", and was different from the comment
which stated "discard up to but not including the closing $".  This
patch fixes that by making the loop:

    do {
        ch = *cp;
        if (ch == '$')
            break;
        cp++;
        rem--;
    } while (rem);

That is, cp is tested _then_ incremented.

This loop exits if it finds a "$" or if it runs out of bytes in the
source.  After this loop, if there was no closing "$" the expansion is
skipped, and the outer loop is allowed to continue leaving this
non-keyword as it was.  However, when the "$" is found, size is
corrected, before running the expansion:

    size -= (cp - src);

This is wrong; size is going to be corrected anyway after the expansion,
so there is no need to do it here.  This patch removes that redundant
correction.

To help find this bug, I heavily commented the routine; those comments
are included here as a bonus.

Under some implementations of echo (such as that provided by
dash), backslash escapes are recognized without any other
options. This means that echo-ing user-supplied strings may
cause any backslash sequences in them to be converted. Using
printf resolves the ambiguity.

This bug can be seen when using git-am to apply a patch
whose subject contains the character sequence "\n"; the
characters are converted to a literal newline. Noticed by
Szekeres Istvan.

In git.git repository, "git-name-rev v1.3.0~158" cannot name the
rev, while adjacent revs can be named.

This was because it gives up traversal from the tips of existing
refs as soon as it sees a commit that has older commit timestamp
than what is being named.  This is usually a good heuristics,
but v1.3.0~158 has a slightly older commit timestamp than
v1.3.0~157 (i.e. it's child), as these two were made in a
separate repostiory (in fact, in a different continent).

This adds a hardcoded slop value (1 day) to the cut-off
heuristics to work this kind of problem around.  The current
algorithm essentially runs around from the available tips down
to ancient commits and names every single rev available that are
newer than cut-off date, so a single day slop would not add that
much overhead in repositories with long enough history where the
performance of name-rev matters.

I think the algorithm could be made a bit smarter by deepening
the graph on demand as a new commit is asked to be named (this
would require rewriting of name_rev() function not to recurse
itself but use a traversal list like revision.c traverser does),
but that would be a separate issue.

A few new configuration options grew out of the woodwork during the

of, so we do so.

I wanted to also add completion support for the <driver> part of

strings would be.  Since this appears to be non-trivial I'm punting
