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.
