Somebody has a pattern matching problem. He says "I know, I'll use
regular expressions for it". Now he has two problems. SCNR.
In short: it is not beautiful, but I don't see how this could be
improved. And a problem with the above is that \` only matches at
position 0 of a string, not at the point where you start matching. So
you need to explicitly digest the string with "substring" while
parsing to keep this working.
Perhaps the starting index of a string match should match on \= in
analogy to the "starting index" of a buffer match?
But that's just an aside note.
