Hmm, according to my understanding of the code, the only thing "isalpha"
prevents is a non-alpha in the protocol portion of a full URL, i.e.

  rect http2://foo/bar 

wouldn't work.  This code is just a test to see if the URL given is a full or
relative one; when it finds a non-alpha, if it's a ':', it presumes it is an
absolute URL.  But since no URL scheme out there uses numbers (yet?!) this is
fine.  

At least as best as I can tell; my .map files have files with numbers in them
all over.
