You can always use the `-e' option and then have a look at the $words
array, which is one of the special parameters set by the completion
code. It contains the word on the line. So:

  zstyle -e ':completion:*:complete:rm:*' file-patterns '
    if (( $words[(I)-r] )); then                                               

This doesn't catch the case where the `-r' option is put together with
other options in the same string (like `-ir').

Even if there were a function for `rm' which would do option parsing,
there currently were no way of smuggling code into it to take
advantage of the information about options on the line gathered there.
Except for that `-e' thing above (if a `_rm' function would use
_arguments we should have $opt_args available inside that code).
