Well, bugs are usually fixed within days after they have been
reported. Otherwise they are usually documented in the code or in the
documentation or in the test suite (with test_expect_failure).

For the rest we rely on people remembering what happened and on
people's mailing list searching skills ;-)

I think you have to alias "git bisect-stop".

I am not sure because when I use aliases I prefer to use shell aliases like:

alias gst='git status'

Yes, it is symmetric, so we cannot just automatically reverse the
meanning because there is no "after" or "before" relationship between
"dev" and "master".
