URLs with underscores

[Angie Ahl]

Just to let you know I've changed my copy of markdown (syntax below) to 
check for a \b (word break) before the first *|_ as it was becoming a 
real problem with my stuff.

We have a lot of URL's with 2 _ in them.

It's working beautifully and will be tested with many different types 
of input so I'll let you know if we find any circumstances where it 
doesn't work well.

sub _DoItalicsAndBold {
	my $text = shift;

	# <strong> must go first:
	$text =~ s{ (\*\*|__) (?=\S) (.+?[*_]*) (?<=\S) \1 }
		{<strong>$2</strong>}gsx;

	$text =~ s{ \b(\*|_) (?=\S) (.+?) (?<=\S) \1 }
		{<em>$2</em>}gsx;

	return $text;
}
