Subject: [PATCH] feat(tools/cheddar): shortlink depot revisions

r/3000 will now be shortlinked to show the commit in cgit. Going via
atward probably doesn't make sense at this point, since the depot refs
are not available in sourcegraph at all (for reasons I can't
repeat). Switching to atward might be interesting when/if we introduce
support for shortlinking // paths.

Fixes: b/163
Change-Id: I57c1a7d02d881e4f8b3ee1f71755dd7930925dc4
