Let git-checkout save the old branch as a symref in LAST_HEAD, and
make 'git checkout -' switch back to LAST_HEAD, like 'cd -' does in
the shell.

/me likes this feature.

git rebase (-i or not) calls checkout behind the scenes if the
two-argument form is used:

   git rebase [-i] master topic

and 'topic' is not the current branch. You may want to add a test that
ensures that rebase sets LAST_HEAD in this case.

You must make sure that commits referenced by LAST_HEAD are not
garbage-collected. (I don't know if this happens anyway for symrefs in .git.)

Note: if you used reflogs for that feature, the garbage collection could 
not have killed the commit.  However, it is quite possible that the 
branch was deleted.
