No resetting of $. on implicit close

The documentation for Perl 5.0 has always stated that $. is not reset when an already-open file handle is reopened with no intervening call to close. Due to a bug, perl versions 5.000 through 5.003 did reset $. under that circumstance; Perl 5.004 does not.

Next: wantarray may return undef

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