I'd like this, too. Even for meld, which _can_ do tree diffs. The
reason is to show the tree diff, Hg sets it up with two temp dirs
holding only the differing files. This means I cannot use it to
selectively undo changes against the real file in the working copy
with ease.

(Of course, newer hgtk alleviates this somewhat.)
