completion fix

[Tom Tromey <tromey@cygnus.com>]

I'm debugging gcj.  I bring up the console and type:

b build_jni<Tab>

There is only one function that this can possibly complete.  Insight
changes it to "b build_jni_stub" and beeps.

This annoyed me, so I looked at the code.  I added some debugging
prints and it turns out that the switch statement was written
incorrectly.  Also, the `1' branch had an obvious bug.  (Code like
`switch {' is almost always wrong.  I didn't grep through the source
to see if this error is in more than one place.)

Here is a patch.

(BTW I gave myself write permission for the `src' repo on sourceware,
because I had some dejagnu patches to check in.  So if you want I can
commit this myself.  If you'd rather not, that is also fine -- it
doesn't matter to me.)

	* console.itb (Console::_complete): Dequoted first argument to
	switch.  Window name is `$_twin', not `_twin'.
