[doc] missing T_PTR_SPECIAL example in perlxs

[djerius]

Where

perlxs

Description

The documentation for the OVERLOAD: keyword, third paragaraph, last line, reads:

See the sample for T_PTROBJ_SPECIAL below.

Unfortunately there is no sample for it below. There used to be; it was present in the Typemap section in Perl 5.14; but disappeared in Perl 5.16.

[djerius]

The sample was moved to perlxstypemap; replacing below with a reference to that document would fix it.
