Copy/paste works fine :-) Seriously, I did think about it, but a couple
of cases test more than one string so a totally trivial helper wouldn't
do and I couldn't be bothered doing anything more complicated while
under influenza :-) You are welcome to do something nicer for .32.

BTW. While at it, I think we should move that stuff to a separate
subdir too.

Cheers,
Ben.
