These are all good revsets. I'm glad someone other than me is actually
using revsets! They're a very powerful DSL for inspecting hg history.

By the way, newer Mercurial versions allow revsets in hgweb searches,
so that we could use urls that contain revset queries. This would
require upgrading Savannah's Debian OS, which should be done anyway.
Is there interest in this? If so, I could consult with the Savannah
hackers about doing server upgrades.
