Bug#930129: split: if no PATTERN is given, say EXPR defaults to $_ also

[積丹尼 Dan Jacobson]

Package: perl-doc
Version: 5.28.1-6
Severity: minor
File: /usr/share/man/man1/perlfunc.1.gz

$ perldoc -f split|fgrep \$_
            If only PATTERN is given, EXPR defaults to $_.

Say instead
            If only PATTERN is given, or if no PATTERN is given, EXPR defaults 
to $_.
