Either change old --exclude into --exclude-regexp and use rsync's --include
--exclude, or keep --exclude as it is, and add --select that uses a +/- at
the front to indicate include/exclude.

Keeping a regexp option does complicate the matching, but I could add
something like it to dirscan... It does convert efn patterns to regex's to
do the matching so it shouldn't be too hard.
