R devel - Sep 2019 - Feature request: non-dropping regmatches/strextract

I think that's a good reason for not including this in regmatches;
you're right, its name is somewhat suggestive of yielding matches. Also,
that sounds like a great design for strcapture with an atomic prototype.

After some discussion within R core, we decided that a "nomatch"
argument on regmatches() may be a good initial step. We might add a
new function later that combines the regexpr() and regmatches() steps.
The gregexpr() and regexec() inputs are both lists so it's not clear
whether a "nomatch" value would be relevant (the elements are empty)
in those cases.
