Well, I think that is a feature more than a hurdle. :)

As I said, it doesn't quite seem the right place. We do have 'make
clean' already, though that won't work on Windows, because 'rm' doesn't
handle unicode characters. We could update 'make clean' to be a little
bit better.

Again, I'm not opposed to it entirely, but I don't really want all of
our commands to be able to do the same things if you just supply the
right options. :) (bzr merge --unmerge --uncommit --revert --clean-tree
--remove-tree)
