When a repository otherwise properly prepared is served by a
dumb HTTP server that sends "No such page" output with 200
status for human consumption to a request for a page that does
not exist, the users will get an alarming "File X corrupt" error
message. Hint that they might be dealing with such a server at
the end and suggest running fsck-objects to check if the result
is OK (the pack-fallback code does the right thing in this case
so unless a loose object file was actually corrupt the result
should check OK).

* jc/merge:
git-merge knows some strategies want to skip trivial merges
generate-cmdlist: style cleanups.
Add missing semicolon to sed command.
unpack_delta_entry(): reduce memory footprint.
git.el: Added a function to diff against the other heads in a merge.
git.el: Get the default user name and email from the repository config.
git.el: More robust handling of subprocess errors when returning strings.
Most notably "ours". Also this makes sure we do not record
duplicated parents on the parent list of the resulting commit.
This is based on Mark Wooding's work, but does not change the UI
nor introduce new flags.

This does two things.
* A new flag --reference can be used to name a local repository
that is to be used as an alternate. This is in response to
an inquiry by James Cloos in the message on the list
<m3r74ykue7.fsf@lugabout.cloos.reno.nv.us>.
* A new flag --use-separate-remote stops contaminating local
branch namespace by upstream branch names. The upstream
branch heads are copied in .git/refs/remotes/ instead of
.git/refs/heads/ and .git/remotes/origin file is set up to
reflect this as well. It requires to have fetch/pull update
to understand .git/refs/remotes by Eric Wong to further
update the repository cloned this way.
For the former change, git-fetch-pack is taught a new flag --all
to fetch from all the remote heads. Nobody uses the git-clone-pack
with this change, so we could deprecate the command, but removal
of the command will be left to a separate round.

Currently we unpack the delta data from the pack and then unpack
the base object to apply that delta data to it. When getting an
object that is deeply deltified, we can reduce memory footprint
by unpacking the base object first and then unpacking the delta
data, because we will need to keep at most one delta data in
memory that way.

The point where the line for a parent joins to the first child
shown is visually different from the lines to the other children,
because the line doesn't branch, but terminates at the child.
Because of this, we now treat the first child a little differently
in the optimizer, and we draw its link in drawlineseg rather
than drawparentlinks. This improves the appearance of the graph.

The updated code reads the tip of the current branch before and
after the import runs, but forgot to chomp what we read from the

It seems Tk 8.4 can't draw arrows on diagonal line segments. This
adds code to the optimizer to make the last bit of a line go vertically
before being terminated with an arrow pointing downwards, so that
it will be drawn correctly by Tk 8.4.

* master:
3% tighter packs for free
Rewrite synopsis to clarify the two primary uses of git-checkout.
Fix minor typo.
Reference git-commit-tree for env vars.
Clarify git-rebase example commands.
Document the default source of template files.
Call out the two different uses of git-branch and fix a typo.
Add git-show reference
This patch makes for 3.4% smaller pack with the git repository, and
a bit more than 3% smaller pack with the kernel repository.
And so with _no_ measurable CPU difference.

Documentation says -i is "import only", so without it,
subsequent import should update the current branch and working
tree files in a sensible way.
"A sensible way" defined by this commit is "act as if it is a
git pull from foreign repository which happens to be CVS not
git". So:
- If importing into the current branch (note that cvsimport
requires the tracking branch is pristine -- you checked out
the tracking branch but it is your responsibility not to make
your own commits there), fast forward the branch head and
match the index and working tree using two-way merge, just
like "git pull" does.
- If importing into a separate tracking branch, update that
branch head, and merge it into your current branch, again,
just like "git pull" does.

As pointed out by Junio, it may be dangerous to cut off people's names
after 15 bytes. If the name is encoded in an encoding which uses more
than one byte per code point we may end up with outputting garbage.
Instead of trying to do something smart, just output the entire name.
We don't gain much screen space by chopping it off anyway.
Furthermore, only output the file name if we actually found any
renames.

When fetching alternates, http-fetch may reuse the slot to fetch non-http
alternates if http-alternates does not exist. When doing so, it now needs
to update the slot's finished status so run_active_slot waits for the
