-LONG_USAGE='git bisect help
-	print this long help message.
-git bisect start [--term-{old,good}=<term> --term-{new,bad}=<term>]
-		 [--no-checkout] [<bad> [<good>...]] [--] [<pathspec>...]
-	reset bisect state and start bisection.
-git bisect (bad|new) [<rev>]
-	mark <rev> a known-bad revision/
-		a revision after change in a given property.
-git bisect (good|old) [<rev>...]
-	mark <rev>... known-good revisions/
-		revisions before change in a given property.
-git bisect terms [--term-good | --term-bad]
-	show the terms used for old and new commits (default: bad, good)
-git bisect skip [(<rev>|<range>)...]
-	mark <rev>... untestable revisions.
-git bisect next
-	find next bisection to test and check it out.
-git bisect reset [<commit>]
-	finish bisection search and go back to commit.
-git bisect (visualize|view)
-	show bisect status in gitk.
-git bisect replay <logfile>
-	replay bisection log.
-git bisect log
-	show bisect log.
-git bisect run <cmd>...
-	use <cmd>... to automatically bisect.
