It still says "The following SVN commands are ..."

I've never read that web page or looked at contrib/reghunt before, but
most of it can probably be done by 'git bisect' run. The web page
should be rewritten in terms of using git bisect. I can take a stab at
that if nobody else wants to.

It's possible that the various contrib/reghunt/bin/gcc-test-* helper
scripts could still be useful with 'git bisect run' as the building
blocks for a script that checks a given revision.
