If anything, what is missing a some more documentation in `match-beginning'
explaining that the match data is "ephemeral" and can be changed by most
functions other than very basic ones that obviously don't use regexps (like
`car'). It's generally a lot easier to fix the very few places where
this ephemerality is a problem than to add `save-match-data'
around everything.
