* 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.

This turns out to be slightly simpler and faster, and will make
things a little easier when we do multiple view support.

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.

Before this patch git-blame <directory> gave non-sensible output. (It
assigned blame to some random file in <directory>) Abort with an error
message instead.

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.

If the user does not set a merge strategy for git-pull,
let git-merge calculate a default strategy.

The rotating 64-bit number was not really rotating, and worse
yet ulong was longer than 64-bit on 64-bit architectures X-<.

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
non-http alternates request to finish.

* fk/blame:
blame: Rename detection (take 2)
rev-lib: Make it easy to do rename tracking (take 2)
Make it possible to not clobber object.util in sort_in_topological_order (take 2)
The "score" calculation for diffcore-rename was totally broken.
It scaled "score" as
score = src_copied * MAX_SCORE / dst->size;
which means that you got a 100% similarity score even if src and dest were
different, if just every byte of dst was copied from src, even if source
was much larger than dst (eg we had copied 85% of the bytes, but _deleted_
the remaining 15%).
That's clearly bogus. We should do the score calculation relative not to
the destination size, but to the max size of the two.
This seems to fix it.

This tweaks the maximum hashvalue we use to hash the string into
without making the maximum size of the hashtable can grow from
the current limit. With this, the renames detected becomes a
bit more precise without incurring additional paging cost.

To reduce wasted memory, wait until the hash fills up more
densely before we rehash. This reduces the working set size a
bit further.

Marco Costalba reports that --remove-empty omits the commit that
created paths we are interested in. try_to_simplify_commit()
logic was dropping a parent we introduced those paths against,
which I think is not what we meant. Instead, this makes such
parent parentless.

which I think is not what we meant. Instead, this marks such
parent uninteresting. The traversal does not go beyond that
parent as advertised, but we still say that the current commit
changed things from that parent.

This changes diffcore-rename to reuse statistics information
gathered during similarity estimation, and updates the hashtable
implementation used to keep track of the statistics to be
denser. This seems to give better performance.

Some versions of gcc check that calls to the exec() family have the proper
sentinel for variadic calls. This should be (char *) NULL according to the
man page. Although for all other purposes the 0 is equivalent, gcc
nevertheless does emit a warning for 0 and not for NULL. This also makes the
usage consistent throughout git.
The whitespace in function calls throughout imap-send.c has its own style,
so I left it that way.

RPM, at least on Fedora boxes, automatically creates a
dependency for any perl "use" lines, and one of the help text
lines unfortunately begins like this:
-S, --rev-file revs-file
use revs from revs-file instead of calling git-rev-list
RPM gets confused and creates a false dependecy for the
nonexistent perl package "revs". Obviously this creates a
problem when someone goes to install the git-core rpm.
Since other help sentences all start with capital letter, make
this one match them by upcasing "Use". As a side effect, RPM
stops getting confused.
