But does it cope with the Guides? Should it cope if spelt that way?

git help revisions
git revisions --help

Hmph.  Ralf's patch is not just "I wonder if we could do a bit
better" but is also a regression.  I do not particularly care
if the latter stops working, but the former definitely should,
as "git help -g" encourages readers to type that, but with the
change "git help <concept>" seems to stop working.
