Update in perlop

Hello all,

In the section: http://perldoc.perl.org/perlop.html#Auto-increment-and-Auto-decrement

I believe this line is incorrect:
"undef is always treated as numeric, and in particular is changed to 0 before incrementing (so that a post-increment of an undef value will return 0 rather than undef)."

Upon testing:
$ perl -le '$val=undef;print("Initial Value: $val");$val++;print("Incremented Value: $val");'
Initial Value:
Incremented Value: 1

It seems that the post-increment value of undef will be 1, not 0 as the documentation states.

Regards,
Prateek
