Whatever the name is, we should make sure they don’t introduce even more 
confusion on top of the already confusing names.

re-search-forward
re-search-backward
re-search
re-match

It’s hard to see what each function does from a glance, IMO. That’s not 
counting string regexp functions.

It would be cool if these functions accept rx forms.
