(Fexpand_file_name): In the no-handler case, after

expanding, look again for a handler and invoke it.  This is needed
for filenames like "/foo/../user@host:/bar/../baz" -- the first
expansion produces "/user@host:/bar/../baz" which needs to be
expanded again for the finame result "/user@host:/baz".
