Only in lisp/cedet/, I think.  I'm guessing this is the result of
integrating CEDET.  If you want the details, maybe the CEDET people
and/or Chong (which did most of the work) could tell you the reasons
for that.  I suggest to look at Git logs and maybe ask them Or maybe
Glenn (CC'ed) remembers.

Probably because the range of versions you tried to bisect didn't
touch the others.  It obviously depends on which files whose autoloads
are there are modified by the commits you are bisecting.

It's documented in the ELisp manual.  Which parts are unclear?
