Subject: [PATCH] (gnus-compile): Modify the actual format specs as well;
 don't bind `gnus-tmp-func'.
 (gnus-update-format-specifications): Use
 `gnus-update-format-specification-1'.
 (gnus-update-format-specification-1): New function.
 (gnus-format-specs-compiled): Modify the form. (TopLevel):
 Require `alist'. (gnus-compile): Don't modify the value of
 `gnus-format-specs', generate compiled specs in
 `gnus-format-specs-compiled' instead; don't touch the
 dribble buffer. (gnus-format-specs-compiled): New internal
 variable.
