> This is totally inappropriate.  Emacs is trying to be too clever here.
> A backslash before `*' or a paren can mean any number of different
> things in a doc string.
> Consider this bit of a doc string, for instance:
>  When both optional args are non-nil, the `find' command run is this:
>    find . -mindepth MIN-DEPTH -maxdepth MAX-DEPTH
>           \\( -path \*edir1\* -o -path \*edir2\* ... \\)
>           -prune -o \\( ARGS \\) LS-SWITCHES"
> It makes zero sense for `\*' here to have its backslash highlighted.
