I have committed the change in master
(9763857d8857a14f2a20c05e5ed552ca47bba3d8). (my git-fu is weak, and the
changeset is small, so I manually made the change and committed, instead
of pulling)

I have also added support for evaluation of '$STY' (the next commit),
which might also be useful for some tasks.

Thanks for the patch! Feel free to send additional patches for useful
things! ;)
