Synced PseudoPerldoc process() code with Pod::Perldoc >= 3.21_01

This commit reverted changes of r19825 (commented out failing code)

Patch previously was submitted to [Padre maillist](http://mail.perlide.org/pipermail/padre-dev/2014-April/003593.html)
Padre requires 'Pod::Perldoc' => '3.23', so this is not possible
