The issue I worry about is it hitting between changes and their fixup.
e.g. for example if I find that specific change doesn't compile in some special
configuration then I amend it to fix that. Alternatively I could put in a fixup
commit afterwards, but then if someone did bisect and the bisect hit inbetween
the change and the fixup they might end up with a tree that doesn't compile.
