Yes, I didn't mean to say "bisect run" is always great.  What I was
hinting at was that even if you are _not_ using "bisect run" (which
almost always _requires_ you to write a small script that does the
test and says yes/no), once you start working on a project that is
sufficiently complex (like bisecting a regression in the Linux
kernel), your procedure to build and test a single revision becomes
complex enough that it is worth to write and use a small script for
a single step _anyway_.  And with that in mind, "how do I prepare
the checked-out tree for building and testing" can be part of that
script.

Which in turn means there is nothing to add to "bisect", not even
the "--fixup my_fixup_script" I alluded to, let alone "--merge-to"
that is way too specific to the case you happened to have had before
you sent your message.
