MFC r196558: Don't try to mmap the contents of empty files.  This behaviour
was harmless prior to r195693, when mmap(2) changed from silently ignoring
requests for mapping zero bytes to returning EINVAL; this commit can be seen
as adjusting for the change in mmap(2) in order to make look(1) act like it
did previously.
