Minor patch to 3.0.4 for ALWAYS_LAST_PROMPT

[Bart Schaefer <schaefer@xxxxxxxxxxxxxxxxxxxxxxx>]

I'm sure I sent some mail about this quite a while ago -- probably
back in February, judging by the edit dates on some files.

The manual entry for ALWAYS_LAST_PROMPT says:

                     If  unset,  key  functions that list comple-
                     tions try to return to the  last  prompt  if
                     given a numeric argument. If set these func-
                     tions try to return to the  last  prompt  if
                     given no numeric argument.

What the code does, however, is act this way if an argument *other*
*than 1* is given.  That is, ESC 2 ... or even ESC 0 ... produces the
desired effect, but ESC 1 ... does not.

The fix is to look at `gotmult', rather than comparing `zmult' to 1.
Here's a patch against 3.0.4; I don't know where it applies to 3.1.x.
