Bold and Italic Regexps fail across newlines

[justus@…]

Given input like:

_some italicized
text with a line break_

BlueCloth fails to render it properly. The perl Markdown will put tags around the entire text.

This can be fixed easily by adding the "m" modifier to the BoldRegexp? and ItalicRegexp? variables to cause them to look beyond a newline for the closing part of the Markdown tag.
