bisect: handle search for bad to good transitions
Automatically detect whether we're looking for a bad to good
transition rather than the usual good to bad transition by detecting
when badrev is inside the good set and flipping good/bad.
Basic install:
$ make # see install targets
$ make install # do a system-wide install
$ hg debuginstall # sanity-check setup
$ hg # see help
