I need this from time to time when experimenting with StGit -- or, more precisely, when cleaning up afterwards in case it didn't go so well. Packed refs means I can't safely just edit/delete files under .git/refs anymore, so I use update-ref instead. And having to use the safety belt every time is just plain tedious. I'd say this is a perfect example of when using the plumbing by hand is really what you want.

(In this kind of situation, branch -D often doesn't work since my ref isn't under refs/heads, and besides I really don't want any of it's smarts right then -- I want to delete a ref, nothing more.)

Better suggestions welcome, of course.
