perl files: clean up warnings

Clean up some perl warnings, some of which were legitimate (apparently
undef doesn't actually take a list of arguments, a common enough
mistake that it is mentioned in the man page!, and a list of variables
after "my" can be cantankerous), and some of which were nuisance but
were easy enough to clean up.

Maybe this can resolve the problems with very old version of Perl?
