reference: use named capturing groups
Rewrite the regular expressions to use named capturing groups.
This simplifies handling the resulting matches, but does require
some additional handling to associate matches with their names.
Also making some changes to the matching to match how domains
are _actually_ matched; some of that was already handled in
code parsing the results of the regex, but now this is handled
by the regex itself.
