Make Switch.pm skip POD like perl does

Patch provided by Daniel Klein <danielklein-à-airpost.net> :

  It also doesn't check for invalid POD which gets ignored by the
  compiler anyway.

Seems that Damian had a POD parser in mind when he devised those
regular expressions, but perl only looks for =cut followed by a
non-letter.
