Hmph. Perhaps we can view it as part of reverting 527ec39 and then
redoing it in shell. The way the shell script accumulates matchgrp
variable (i.e. the literal LF in ${var:+string}) makes me feel some
possible portability scare, which might be solved in a more stupid
(i.e. not giving various reimplementations of Bourne shells a chance
to screw it up) way by using another temporary file, but other than
that the resurrected script looks OK to me.
Thanks.
