The rewrite done while adding the shorthand support made the remote
refname recorded in the commit message too long for human consumption,
while losing information by using the shorthand not the real URL to
name the remote repository there.  They were both bad changes done
without enough thinking.

If somebody tries to run `git update-cache foo', where foo is a new
file, git dies with a rather cryptic error message:

 fatal: Unable to add foo to database

This trivial patch makes git explain what probably went wrong.  It is
not a perfect diagnosis of all error paths, but for 90% of the cases it
should provide the user with the clue they need.

[jc: I ended up wording slightly differently, and fixed another
 confusing error message I noticed while reviewing the code.]

Imports a project history from one or more Arch repositories, following
the branching and tagging across repositories. Note you should import
separate projects to separate GIT repositories.

Supported
 - Imports, tags and simple commits.
 - File renames
 - Arch tags
 - Binary files
 - Large trees
 - Multiple repositories
 - Branches

TODO:
 - Allow re-running the import on an already-imported project
 - Follow merges using Arch data
 - Audit shell escaping of filenames
 - Better support for file metadata
 - Better/safer creation of temp directories

Unsupported:
 - Arch 'configuration'

[jc: my arch/tla is very rusty and after Tom announced he is stepping
 down as the maintainer I have very little motivation to relearn it,
 so I would appreciate if people discuss any bugs or enhancements
 directly with Martin.  Of course I can help with the git end of the
 issues.]

Linus says:

    I'm testing bisection to find a bug that causes my G5 to no longer boot,
    and during the process have found this command line very nice:

	    gitk bisect/bad --not $(cd .git/refs ; ls bisect/good-*)

    it basically shows the state of bisection with the known bad commit as the
    top, and cutting off all the good commits - so what you see are the
    potential buggy commits.
Signed-off-by: NJunio C Hamano <junkio@cox.net>

When testing bisection and using gitk to visualize the result, it was
obvious that the termination condition was broken.

We know what the bad entry is only when the bisection ends up telling us
to test the known-bad entry again.

Also, add a safety net: if somebody marks as good something that includes
the known-bad point, we now notice and complain, instead of writing an
empty revision to the new bisection branch.

Earlier we always prefixed refs/heads to the token given to "git fetch"
(and "git pull") as refspec.  This was a mistake.  Allow them to be

When we resolve a merge between two branches, and it removes a file in the
current branch, we notify the person doing the resolve with a big nice
notice like

	Removing xyzzy

which is all well and good.

HOWEVER, we also do this when the file was actually removed in the current
branch, and we're merging with another branch that didn't have it removed
(or, indeed, if the other branch _did_ have it removed, but the common
parent was far enough back that the file still existed in there).

And that just doesn't make sense. In that case we're not removing
anything: the file didn't exist in the branch we're merging into in the
first place. So the message just makes people nervous, and makes no sense.

This has been around forever, but I never bothered to do anything about
it.

Until now.

The trivial fix is to only talk about removing files if the file existed
in the branch we're merging into, but will not exist in the result.

This originally came from Frank Sorenson, but with a bit of rework to
allow future enhancements without changing the external interface for
pack pruning part.

With the '-a' option, all objects in the current repository are packed
into a single pack.  When the '-d' option is given at the same time,
existing packs that were made redundant by this round of repacking are
deleted.

Since we currently have only two repacking strategies, one with '-a'
(everything into one) and the other without '-a' (incrementally pack
only the unpacked ones), the '-d' option is meaningful only when used
with '-a'; it removes the packs existed before we did the "everything
into one" repacking.  At least for now.

Earlier show-branch gave names only to commits reachable via first
parent ancestry chain.  Change the naming code to name everybody.

The original idea was to stop at the first merge point in the
topological order, and --more=<n> to show commits until we show <n>
more extra merge points.  However depending on the order of how we
discover the commits, it additionally showed parents of the <n>th
merge points, which was unnecessary.

This attempts to minimally cope with a subset of MIME "features" often
seen in patches sent to our mailing lists.  Namely:

 - People's name spelled in characters outside ASCII (both on From:
   header and the signed-off-by line).

 - Content-transfer-encoding using quoted-printable (both in
   multipart and non-multipart messages).

These MIME features are detected and decoded by "git mailinfo".

Optionally, with the '-u' flag, the output to .info and .msg is
transliterated from its original chaset to utf-8.  This is to
encourage people to use utf8 in their commit messages for
interoperability.

Applymbox accepts additional flag '-u' which is passed to mailinfo.

The reverse patch application using "git apply" sometimes is too
rigid.  Since the user would get used to resolving conflicting merges
by hand during the normal merge experience, using the same machinery
would be more helpful rather than just giving up.

Cherry-picking and reverting are essentially the same operation.
You pick one commit, and apply the difference that commit introduces
to its own commit ancestry chain to the current tree.  Revert applies
the diff in reverse while cherry-pick applies it forward.  They share
the same logic, just different messages and merge direction.

Rewrite "git rebase" using "git cherry-pick".

This reverts 6c5f9baa commit, whose
change breaks gcc-2.95.

Not that I ignore portability to compilers that are properly C99, but
keeping compilation with GCC working is more important, at least for
now.  We would probably end up declaring with "name[1]" and teach the
allocator to subtract one if we really aimed for portability, but that
is left for later rounds.
