Junio C Hamano [Sat, 17 Dec 2005 07:19:14 +0000 (23:19 -0800)]
Remove misguided branch disambiguation.

This removes the misguided attempt to refuse processing a branch
name xyzzy and insist it to be given as either heads/xyzzy or
tags/xyzzy when a tag xyzzy exists.  There was no reason to do
so --- the search order was predictable and well defined, so if
the user says xyzzy we should have taken the tag xyzzy in such a
case without complaining.

This incidentally fixes another subtle bug related to this.  If
such a duplicate branch/tag name happened to be a unique valid
prefix of an existing commit object name (say, "beef"), we did
not take the tag "beef" but after complaining used the commit
object whose name started with beef.

Another problem this fixes while introducing some confusion is
that there is no longer a reason to forbid a branch name HEAD
anymore.  In other words, now "git pull . ref1:HEAD" would work
as expected, once we revert "We do not like HEAD branch" patch.
It creates "HEAD" branch under ${GIT_DIR-.git}/refs/heads (or
fast-forwards if already exists) using the tip of ref1 branch
from the current repository, and merges it into the current
branch.

The scripts will also set USAGE and possibly LONG_USAGE before they
source git-sh-setup. If LONG_USAGE isn't set it defaults to USAGE.

If we go this way it's easy to catch --help in git-sh-setup, print the
(long) usage message to stdout and exit cleanly. git-sh-setup can

also be easy to change $0 to basename $0 or something else, if would

Although "git-merge" is advertised as the end-user level command

for minimum set of commands, and finally the tutorial.

technical descriptions can be skipped by a casual reader.

I initially started to review the tutorial, with the objective

merge-recursive: leave unmerged entries in the index.

This does two things.

 - When one branch renamed and the other branch did not, the
   resulting half-merged file in the working tree used to swap
   branches around and showed as if renaming side was "ours".
   This was confusing and inconsistent (even though the conflict
   markers were marked with branch names, it was not a good
   enough excuse).  This changes the order of arguments to
   mergeFile in such a case to make sure we always see "our"
   change between <<< and ===, and "their" change between ===
   and >>>.

 - When both branches renamed to the same path, and when one
   branch renamed and the other branch did not, we attempt
   mergeFile.  When this automerge conflicted, we used to
   collapse the index.  Now we use update-index --index-info
   to inject higher stage entries to leave the index in unmerged
   state for these two cases.

What this still does _not_ do is to inject unmerged state into
the index when the structural changes conflict.  I have not
thought things through what to do in each case yet, but the
