This option makes it possible to see all the potential bisection
points. The best ones are displayed first.

Would it not be better to pass --bisect-vars a list of commits that we do
not want to see?  It could then mark them as "DUNNO", and still just
output a single commit.

The problem is that after --bisect-vars we already pass some "good" and then 
a bad commit. So we have to use another flag like --bisect-dunno and put 
the dunno commits after this one.

Then there is the problem that revision.c reorders arguments and doesn't 
know about "--bisect-*" flags. It is also used by a lot of other commands.

After struggling with revision.c for some time, I thought it would be 
simpler and safer to come up first with something in shell.

Also please note that in some cases we cannot just output a single commit, 
because we just dunno which commit is the first bad one.

IMHO such a logic does not belong into a shell script, but into the C
core.

There is a lot of the bisect logic implemented in git-bisect.sh already. The 
long term plan is to rewrite it in C, but I am not sure that the "dunno" 
logic should be the first part of it to be done in C.

Also I thought it was still fine to prototype new features in shell.

Best regards,
Christian.
