That seems to fall apart on "http://example.com" and "http://example.com/foo// 
". I tried to throw something together earlier: I couldn't manage  
without initially breaking it up into scheme/authority/path/query/ 
fragment, after which the following worked fine (on the path alone):

/
	\/([^\/\?\#]+)\/*
$/x
