BUG: listmatches called with bogus list

BUG: listmatches called with bogus list

[Zoltan Hidvegi]

Here is the bug:

% zsh -f
bolyai% setopt autolist                                             
bolyai% bindkey '^[[19~' where-is 
bolyai% 
Where is: kill-_
BUG: listmatches called with bogus list

As I remember, it is somewhere in Zefram's code which causes this bug (i.e. it
is not present in beta10).

I forgot to mention that the the actual message cames when I press TAB or
newline.

Yup.  I put in a sanity check, because of the previous bug or two that
it would catch (and because of the possibility of there being more such
bugs, of course).

In this case, the sanity check got it wrong.  The list is absolutely
fine.  It's just that validlist wasn't set.  You can observe this: type
"ls <tab>", so that a list is formed, then do a where-is, and it will
happily list the editor function names.  Here's the patch:

Time for a bit of defensive programming, I think.

Avoiding the error message was simple but finding out how to avoid the 
display bug that showed up after that...
