That would amount to certain volume of work. How about discarding the
remove-style feature itself, as discussed briefly yesterday? "git grep
TeX-remove-style" reveals that TeX-remove-style is used only in
TeX-arg-document. Until make-variable-buffer-local was removed from
TeX-remove-style-hook, everything went well. That means that
remove-style feature almost didn't work at all until then and no one was
bothered by it.

I think that it's enough to replace
  (setq TeX-style-hook-applied-p nil)
in TeX-arg-document. In this way, we can discard all codes related to
"TeX-remove-style*" in AUCTeX altogether.

More conservative approach is to add another optional argument to
TeX-normal-mode to suppress binding TeX-auto-save to t, and replace
call to TeX-remove-style with TeX-normal-mode, with that new argument
being non-nil.

What do you think about these ideas?
