parse-options: make sure argh string does not have SP or _
We encourage to spell an argument hint that consists of multiple
words as a single-token separated with dashes. In order to help
catching violations added by new callers of parse-options, make sure
argh does not contain SP or _ when the code validates the option
definitions.
