Also, FWIW, I use such a hook in my .emacs and have found it
occasionally harmful, e.g. when editing the emacs/test/indent/scheme.scm
file, which then gets it `execute' bit set, even though it's not meant
to be executed.
Tho I guess it'd be OK to mark those files as executable, but I can't
get myself to do it, so I regularly end up "chmod -x"ing those files
after editing them.
