Allow Whitespace in L<> URLs?

[David E. Wheeler]

Poders,

RT #93491 (https://rt.cpan.org/Ticket/Display.html?id=93491) reports that URLs 
are mis-formatted when they contain a newline. Turns out, the regex that 
detects a URL in L<> explicitly forbids whitespace:

            next unless $ell->[$_] =~ m/^(?:([^|]*)\|)?(\w+:[^:\s]\S*)$/s;

I think that is probably sane, but maybe there are other opinions? Should we 
allow whitespace in L<> URLs? If so, I think we would just change \S to .

Thoughts?

David
