I am not sure to understand fully.
You want to write something like "foo([\r\n]|$)"?
It isn't possible with the standard string library, because the regex 
engine is simple and doesn't support alternatives.
It won't be improved toward this goal (it would need a very different 
algorithm, much bigger), so you would need either more code around the 
matching code (like I did in a parser) or to use a third party regular 
expression library (there is a PCRE binding).
