This allows a single stash entry to be deleted. It takes an
optional argument which is a stash reflog entry. If no
arguments are supplied, it drops the most recent stash entry.

Here is the same patch rebased on top of next.
This doesn't work perfectly yet. One or both of refs/stash and
logs/refs/stash are not being updated correctly.
When the top-most stash is dropped, refs/stash is not updated to
contain the commit id of the new stash@{0}. A subsequent drop then
produces a warning like:
warning: Log .git/logs/refs/stash unexpectedly ended on Wed, 6 Feb 2008 10:00:20 -0600.
So this is still a work in progress.
Also missing is the ability to drop multiple stash entries at
one time. I think reflog delete will have to be modified to
accommodate this. What happens is that the deletions are performed
in a loop, and each deletion shifts the reflog entries so that they
don't necessarily point to the same thing.
$ git stash list
stash@{0} My fourth stash
stash@{1} My third stash
stash@{2} My second stash
stash@{3} My first stash
$ git reflog delete stash@{1} stash@{2}
$ git stash list
stash@{0} My fourth stash
stash@{1} My second stash
"My third stash" and "My second stash" should have been deleted, but
"My first stash" was deleted instead.
