Perhaps it's better to add something like this first:

git bisect status
	show the current bisect state

It could tell if we are currently bisecting and show the "good", "bad" 
and "skip"ped revs and the content of the BISECT_START and BISECT_NAMES 
(and perhaps BISECT_RUN) files.

It seems not very friendly to just "return 1" when not bisecting.
And before my last patch to use BISECT_START to check if we are bisecting, 
it would perhaps have been better to use 'test -f "$GIT_DIR/BISECT_NAMES"'.

Thanks,
Christian.
