There are some baseless merge cases where git-merge-recursive will
try to compare one of the branches against the empty tree. However
most projects won't have the empty tree object in their object database
as Git does not normally create empty tree objects. If the empty tree
object is missing then the merge process will die, as it cannot load the
object from the database. The error message may make the user think that
their database is corrupt when its actually not.
So instead we should just create the empty tree object whenever it is
needed. If the object already exists as a loose object then no harm
done. Otherwise that loose object will be pruned away later by either
git-prune or git-prune-packed.
Thanks goes to Junio for suggesting this fix.

The command used to have a safety valve to prevent this sequence:
edit foo
git update-index foo
edit foo
git diff foo
git commit --only foo
The reason for this was because an inexperienced user might
mistakenly think what is shown with the last-minute diff
contains all the change that is being committed (instead, what
the user asked to check was an incremental diff since what has
been staged so far). However, this turns out to only annoy
people who know what they are doing. Inexperienced people
would not be using the first "update-index" anyway, in which
case they would see the full changes in the "git diff".

Data in rr-cache isn't valid after a patch application is
skipped or and aborted, so our next commit could be misrecorded
as a resolution of that skipped/failed commit, which is wrong.
git-am --skip, git-rebase --skip/--abort will automatically
invoke git-rerere clear to avoid this.
Also, since git-am --resolved indicates a resolution was
succesful, remember to run git-rerere to record the resolution
(and not surprise the user when the next commit is made).

Currently the treshold is 5000. The likelihood of this value to ever be
crossed for a single push is really small making it not really useful.
The optimal treshold for a pure space saving on a filesystem with 4kb
blocks is 3. However this is likely to create many small packs
concentrating a large number of files in a single directory compared to
the same objects which are spread over 256 directories when loose. This
means we would need 512 objects per pack on average to approximagte the
same directory cost (a pack has 2 files because of the index).
But 512 is a really high value just like 5000 since most pushes are
unlikely to have that many objects. So let's try with a value of 100
which should have a good balance between small pushes going to be
exploded into loose objects and large pushes kept as whole packs.
This is not a replacement for periodic repacks of course.

Modify cvs-migration.txt so it explains first how to develop against a
shared repository, then how to set up a shared repository, then how to
import a repository from cvs. Though this seems chronologically
backwards, it's still readable in this order, and it puts the more

Remove the annotate/pickaxe section; perhaps it can find a place elsewhere

the introduction.
Add some minor clarifications, including two that have come up several

Without any specification in the .git/config file, git-pull will execute
"git-pull origin"; which in turn defaults to pull from the first "pull"
definition for the remote, "origin".
This is a difficult set of defaults to track for a new user, and it's
difficult to see what tells git to do this (especially when it is
actually hard-coded behaviour). To ameliorate this slightly, this patch
explicitly specifies the default behaviour during a clone using the
"branch" section of the config.
For example, a clone of a typical repository would create a .git/config
containing:
[remote "origin"]
url = proto://host/repo.git
fetch = refs/heads/master:refs/remotes/origin/master
[branch "master"]
remote = origin
merge = refs/heads/master
The [branch "master"] section is such that there is no change to the
functionality of git-pull, but that functionality is now explicitly
documented.

An earlier commit a9cb3c6e changed git-commit to use the
contents of MERGE_MSG even when we do not have MERGE_HEAD (the
rationale is in its log message).
However, the change tricks the following sequence to include a
merge message in a completely unrelated commit:
$ git pull somewhere
: oops, the conflicts are too much. forget it.
$ git reset --hard
: work work work
$ git commit
To fix this confusion, this patch makes "git reset" to remove
the leftover MERGE_MSG that was prepared when the user abandoned
the merge.

Extend git-branch with the following options:

This also indroduces $GIT_DIR/RENAME_REF which is a "metabranch"
used when renaming branches. It will always hold the original sha1
for the latest renamed branch.
Additionally, if $GIT_DIR/logs/RENAME_REF exists, all branch rename
events are logged there.

A new option "--exclude-per-directory=.gitignore" can be used to

Suppose you have changes in new1 to the original lines 10-20,
and changes in new2 to the original lines 15-25, then the
changes to 10-25 conflict. But it is possible that the next
changes in new1 still overlap with this change to new2.
So, in the next iteration we have to look at the same change
to new2 again.
The old code tried to be a bit too clever. The new code is
shorter and more to the point: do not fiddle with the ranges
at all.
Also, xdl_append_merge() tries harder to combine conflicts.
This is necessary, because with the above simplification,
some conflicts would not be recognized as conflicts otherwise:
In the above scenario, it is possible that there is no other
change to new1. Absent the combine logic, the change in new2
would be recorded _again_, but as a non-conflict.

This brings the power of the index up front using a proper mental model
without talking about the index at all. See for example how all the
technical discussion has been evacuated from the git-add man page.
Any content to be committed must be added together. Whether that
content comes from new files or modified files doesn't matter. You
just need to "add" it, either with git-add, or by providing
git-commit with -a (for already known files only of course).
No need for a separate command to distinguish new vs modified files
