Comment (by datallah):

 It just dawned on me that this patch is actually not ok because the buffer
 being returned will get overwritten by a subsequent call to
 purple_normalize() (which would be non-obvious).

 My current thought is that the solution will be a documentation change
 indicating that the returned value from `purple_xfer_get_remote_user` may
 not be normalized, which moves the burden to the consumer.
