This will not be backward compatible no matter how you cut it.
Shelve it for now until somebody comes up with a better way to
determine when we can safely refuse to use the first set of
branchse for merging without upsetting valid workflows.

An earlier commit made "reset --hard" chattier but leaking its
message from "git rebase" (which calls it when first rewinding
the current branch to prepare replaying our own changes) without
explanation was confusing, so add an extra message to mention
it. Inside restorestate in merge (which is rarely exercised
codepath, where more than one strategies are attempted),
resetting to the original state uses "reset --hard" -- this can
be squelched entirely.

Older fsck-objects and prune did not protect commits in reflog
entries, and it is quite possible that a commit still exists in
the repository (because it was in a pack, or something) while
some of its trees and blobs are long gone. Make sure the commit
and its associated tree is complete and expire incomplete ones.

If the user has been using reflog for a long time (e.g. since its
introduction) then it is very likely that an existing branch's
reflog may still mention commits which have long since been pruned
out of the repository.
Rather than aborting with a very useless error message during
git-repack, pack as many valid commits as we can get from the
reflog and let the user know that the branch's reflog contains
already pruned commits. A future 'git reflog expire' (or whatever
it finally winds up being called) can then be performed to expunge
those reflog entries.

* master:
Introduce a global level warn() function.
Rename imap-send's internal info/warn functions.
_XOPEN_SOURCE problem also exists on FreeBSD
parse-remote: mark all refs not for merge only when fetching more than one
git-reset --hard: tell the user what the HEAD was reset to
git-tag: support -F <file> option
Revert "git-pull: refuse default merge without branch.*.merge"
Suggest 'add' in am/revert/cherry-pick.
Use git-merge-file in git-merge-one-file, too
diff --check: fix off by one error
Documentation/git-branch: new -r to delete remote-tracking branches.
Fix system header problems on Mac OS X
spurious .sp in manpages
Like the existing error() function the new warn() function can be
used to describe a situation that probably should not be occuring,
but which the user (and Git) can continue to work around without
running into too many problems.
An example situation is a bad commit SHA1 found in a reflog.
Attempting to read this record out of the reflog isn't really an
error as we have skipped over it in the past.

Because I am about to introduce a global warn() function (much
like the global error function) this global declaration would
conflict with the one supplied by imap-send. Further since
imap-send's warn function output depends on its Quiet setting
we cannot simply remove its internal definition and use the
forthcoming global one.
So refactor warn() -> imap_warn() and info() -> imap_info()
(the latter was done just to be consistent in naming).

An earlier commit a71fb0a1 implemented much requested safety
valve to refuse "git pull" or "git pull origin" without explicit
refspecs from using the first set of remote refs obtained by
reading .git/remotes/origin file or branch.*.fetch configuration
variables to create a merge. The argument was that while on a
branch different from the default branch, it is often wrong to
merge the default remote ref suitable for merging into the master.
That is fine as a theory. But many repositories already in use
by people in the real world do not have any of the per branch
configuration crap. They did not need it, and they do not need
it now. Merging with the first remote ref listed was just fine,
because they had only one ref (e.g. 'master' from linux-2.6.git)
anyway.
So this changes the safety valve to be a lot looser. When "git
fetch" gets only one remote branch, the irritating warning would
not trigger anymore.
I think we could also make the warning trigger when branch.*.merge
is not specified for the current branch, but is for some other
branch. That is for another commit.

This reverts commit a71fb0a141.
The logic to decide when to refuse to use the default "first set of
refs fetched" for merge was utterly bogus.
In a repository that happily worked correctly without any of the
per-branch configuration crap did not have (and did not have to
have) any branch.<current>.merge. With that broken commit, pulling
from origin no longer would work.
Now that we have decided to make 'add' behave like 'update-index'
(and therefore fully classify update-index as strictly plumbing)
the am/revert/cherry-pick family of commands should not steer the
user towards update-index. Instead send them to the command they
probably already know, 'add'.

This prepares a place to collect reflog management subcommands,
and implements "expire" action.
$ git reflog expire --dry-run \
--expire=4.weeks \
--expire-unreachable=1.week \
refs/heads/master
The expiration uses two timestamps: --expire and --expire-unreachable.
Entries older than expire time (defaults to 90 days), and entries older
than expire-unreachable time (defaults to 30 days) and records a commit
that has been rewound and made unreachable from the current tip of the
ref are removed from the reflog.
The parameter handling is still rough, but I think the
core logic for expiration is already sound.

This is a mechanical clean-up of the way *.c files include
system header files.
(1) sources under compat/, platform sha-1 implementations, and
xdelta code are exempt from the following rules;
(2) the first #include must be "git-compat-util.h" or one of
our own header file that includes it first (e.g. config.h,
builtin.h, pkt-line.h);
(3) system headers that are included in "git-compat-util.h"
need not be included in individual C source files.
(4) "git-compat-util.h" does not have to include subsystem
specific header files (e.g. expat.h).

indexing the Linux repository ~150MB pack takes about an hour on OS x
while it's a minute on Linux. It seems that the OS X mmap()

one.
Linus proposed a patch replacing mmap() with pread() bringing index-pack
performance on OS X in line with the Linux one. The performances on
Linux also improved by a small margin.
