1cc2cfff91 Basic "subtree merge --squash" support. 
Instead of merging in the history of the entire subproject, just squash it
all into one commit, but try to at least track which commits we used so that
we can do future merges correctly.

Bonus feature: we can actually switch branches of the subproject this way,
just by "squash merging" back and forth from one tag to another.

43a3951243 New --branch option to split command. 
This is just a handy way to create a new branch from the newly-split subtree.

34a82bda77 test.sh: oops, never intended to count the raw number of commits. 
Just needed to make sure the count was non-zero.

795e730e71 Simplify merges even more aggressively. 
If any one of the parents is the same as the current one, then clearly the
other parent branch isn't important, so throw it away entirely.

Can't remember why I didn't do this before, but if I rediscover it, it
definitely needs a unit test.

49cf82288a Only copy a commit if it has at least one nonidentical parent. 
This is a simplification of the previous logic.  I don't *think* it'll break
anything.

Results in far fewer useless merge commmits when playing with gitweb in the
git project:

git subtree split --prefix=gitweb --annotate='(split) ' 0a8f4f0^^..f2e7330
	--onto=1130ef3

...and it doesn't *seem* to eliminate anything important.

13648af5ee Add 'git subtree merge' and 'git subtree pull'. 
These are simple shortcuts for 'git merge -s subtree' and 'git pull -s
subtree', but it makes sense to have it all in one command.

9a8821ff33 Pass the path using the --prefix option instead of on the command line. 
I like this better.  It's more like git-read-tree and some other commands.

96db2c0448 Okay, that was a little too aggressive. 
Now we only prune out a commit if it has exactly one remaining parent and
that parent's tree is identical to ours.

But I also changed the test to create the initial "-s ours" merge in one
step instead of two, and that merge can be eliminated since one of its
parents doesn't affect the subdir at all, and is thus deleted.

d691265880 Even more aggressive commit trimming. 
Now we cut out a commit if any of its parents had the same tree; just use
that parent in its place.  This makes the history look nice, but I don't
think it's quite right...

768d6d1005 Skip over empty commits. 
But we still need to get rid of unnecessary merge commits somehow...

2c71b7c46d Hmm... can't actually filter rev-list on the subdir name. 
Otherwise we can't keep track of parent relationships.  Argh.

This change makes it "work", but we get a bunch of empty commits.

b77172f814 Add a new --rejoin option. 
The idea is to join the new split branch back into this one, so future
splits can append themselves to the old split branch.  We mark the split
branch's history in our merge commit, so we can pull it back out later.
