doc-diff: add --clean mode to remove temporary working gunk

As part of its operation, doc-diff creates a bunch of temporary
working files and holds onto them in order to speed up subsequent
invocations. These files are never deleted. Moreover, it creates a
temporary working tree (via git-wortkree) which likewise never gets
removed.

Without knowing the implementation details of the tool, a user may not
know how to clean up manually afterward. Worse, the user may find it
surprising and alarming to discover a working tree which s/he did not
create explicitly.

To address these issues, add a --clean mode which removes the
temporary working tree and deletes all generated files.
