I took a small stab at doing some cleaning of the Perl scripts, mainly around
using the more modern (well, modern as in +15 years old) form for open(..),
avoiding global filehandles for passing scalar references and enforcing use
strict.  Some smaller typos and fixes were also included.  It seems my Perl has
become a bit rusty so I hope the changes make sense.  The produced files are
identical with these patches applied, they are merely doing cleaning as opposed
to bugfixing.

The attached patches are against the 0001-0006 patches from Heikki and you in
this series of emails, the separation is intended to make them easier to read.
