Fixed localization of $, $&, etc.

Perl versions before 5.004 did not always properly localize the regex-related special variables. Perl 5.004 does localize them, as the documentation has always said it should. This may result in $1, $2, etc. no longer being set where existing programs use them.

Next: No resetting of $. on implicit close

Previous: Fixed parsing of $$<digit>, &$<digit>, etc.
