If you want to allow the user to say M-x occur-mode RET, then you
need to somehow handle the `occur-mode is called too late' case,
anyway.  Whatever the solution, afterwards you can call occur-mode at
the end of occur-1 :-)

But the logic in occur-1 is really not obvious, so it might not be
easy to handle the too-late case...
