It probably is because I am BK untainted, but 'git clean' sounds as if it would do 'git-ls-files --others | xargs rm -f'.

I used to do 'cvs update -p foo.c >foo.c', and extending git-checkout may be familiar to cvs migrants. The most roundabout way (albeit with perhaps least typing) is:

    git-tar-tree HEAD | tar xf - foo.c

I originally talked about reverting file(s) in the working tree, but I wonder if reverting a cache (eh, index) entry to the state in a committed tree is useful. read-tree with a pathspec to overwrite index entries for specified paths while leaving others intact. We could think of it as undoing git-update-index.
