replaces quite a bit of expr calls with ${parameter#word} constructs,

Because a partial commit is meant to be a way to ignore what are

just record what is in A on the filesystem. The previous patch
made the command sequence to barf, saying that A has not been

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"
and end up with a commit that touches only cache.h (notice the
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.
When --with-tree=<tree-ish> option is specified, names from the
given tree are added to the set of names the index knows about,
so we can treat COPYING file in the example as known.
Of course, there is no reason to use "git rm" and git-aware
people have long time done:
$ rm COPYING
$ git commit -m 'Remove COPYING' COPYING
which works just fine. But this caused a constant confusion.

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.

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.

"git diff" does not record index lines for pure mode changes (i.e. no
lines changed). Therefore, apply --index-info would call out a bogus
error.
Instead, fall back to reading the info from the current index.
Incidentally, this fixes an error where git-rebase would not rebase a
commit including a pure mode change, and changes requiring a threeway
merge.

The "Discussion" section has a lot of useful information, but is a
little wordy, especially for an already-long man page, and is designed
for an audience more of potential git hackers than users, which probably
doesn't make as much sense as git matures. Also, I (perhaps foolishly)
forked a version in the user manual, which has been significantly
rewritten in an attempt to address some of the above problems.
So, remove this section and replace it by a (very terse) summary of the
original material--my attempt at the World's Shortest Git Overview--and
a reference to the appropriate chapter of the user manual. It's
unfortunate to remove something that's been in this place for a long
time, as some people may still depend on finding it there. But I think
we'll want to do this some day anyway.

The descriptions of the various object types should all be a subsection

I cribbed most of this chapter from the README (now core-intro.txt and

too lazy to rewrite it. The audience isn't quite right, though--the
chapter is a mixture of user- and developer- level documentation that
isn't as appropriate now as it was originally.
So, reserve this chapter for stuff users need to know, and move the
source code introduction into a new "git hacking" chapter where we'll
also move any hacker-only technical details.

We used to rely on the fact that cherry-pick would trigger the code path
to set limited = 1 in handle_commit(), when an uninteresting commit was
encountered.
However, when cherry picking between two independent branches, i.e. when
there are no merge bases, and there is only linear development (which can
happen when you cvsimport a fork of a project), no uninteresting commit
will be encountered.
So set limited = 1 when --cherry-pick was asked for.

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.

This adds more proper rename detection limits. Instead of just checking
the limit against the number of potential rename destinations, we verify
that the rename matrix (which is what really matters) doesn't grow
ridiculously large, and we also make sure that we don't overflow when
doing the matrix size calculation.
This also changes the default limits from unlimited, to a rename matrix
that is limited to 100 entries on a side. You can raise it with the config
entry, or by using the "-l<n>" command line flag, but at least the default
is now a sane number that avoids spending lots of time (and memory) in
situations that likely don't merit it.
The choice of default value is of course very debatable. Limiting the
rename matrix to a 100x100 size will mean that even if you have just one
obvious rename, but you also create (or delete) 10,000 files, the rename
matrix will be so big that we disable the heuristics. Sounds reasonable to
me, but let's see if people hit this (and, perhaps more importantly,
actually *care*) in real life.
