With Aleksey Cheusov’s patch, this can be fixed by using libc regexp,
but ideally I would like mawk’s internal regexp to handle this, too.
I have a skeleton of an implementation mocked up, but I stopped when
the relationship between REcompile and RE_lex started getting ugly and
I ran out of time. How should the pair of interval endpoints be
passed from RE_lex to REcompile? And how should they be stored on the
op_stack? Ideas welcome.
