Request reverting some from git-pb

Petr, please do not do these name clean-ups yet, _especially_
without having GIT mailing list discussion about renaming.  This
kind of change inevitably introduces merge conflicts.

I suspect this is something you lifted from the larger
libification patch.  While I think name cleanups are good in the
long run, I do not see value in lifting only some name cleanups
from a larger libification patch and having people to adjust for
the merge conflicts twice.  I would not mind if these renames
happen as a part of libification as a whole.  Pending patches
need to be inspected and adjusted when that happens anyway.  But
not until then, at least please have a courtecy to give people a
bit of warning and an opportunity to speak out.
