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)
@vlet : ok . I guess I'll have to bump the dependency on perl for the next version of padre. 

For now, the patch I've applied let people backport padre 1.0 to wheezy (perl 5.14), but it does not make sense for padre git repo.

Thanks for the heads-up.

All the best
