It would be nice if you could move some part of the above note into
the commit message (above the ---). For example:

"Make it possible to implement bisecting only on first parents or on
merge commits by passing flags to find_bisection(), instead of just a
find_all boolean".

While at it maybe the subject line of the commit message could start
with "bisect: create 'bisect_flags' parameter ..." so that we can
quickly tell which area of the code it is about.

I think it's better to use "unsigned int" rather than just "int" for flags.

Is BISECT_FIND_ALL really related to the other flags, or is this
mixing rev list flags with bisect flags?

Thanks for working on this,
Christian.
