Essentially, I'm doing the following:

(clim:define-presentation-method clim:accept ((TYPE my-prestype) STREAM
VIEW &key DEFAULT DEFAULT-TYPE)
  VIEW DEFAULT DEFAULT-TYPE
  (clim:complete-input
   STREAM
   #'(lambda (STRING ACTION)
       (clim:complete-from-possibilities
	STRING 
	*MY-POSSIBILITIES*
	nil
	:action ACTION
	))
     ;;; :allow-any-input t
   )
  )

As always, thanks; but this doesn't seem to really address the problem I'm
trying to solve (perhaps I'm missing the point).

1] If I understand "partial completers" or "delimiters" they define the
delimiters for "sub-strings" on which completion is allowed.  For exmample
defining "-" as a "delimiter" would allow me to type "F-B-B" when I want to
complete on the name "FOO-BAR-BAZ".

I use this feature, but it doesn't seem to help with the problem described
above. 

2] Furthermore, using any of the activation gestures in the standard way
still leaves the "unwanted completion" problem.

For example, suppose "FOOBAR" is a completable name.  If I type "FOO" and
hit return, I'd like to get *only* "FOO" back.  However, the way it works
now, I automatically get the (completed) "FOOBAR".

Again, the behavior I'm trying to achieve is something like the following:
If I type "FOO" and hit (say) space, I'd expect it to complete to "FOOBAR"
(but not neccessarily return the value).  On the other hand if I type "FOO"
and hit return, I'd like it to return just "FOO".

Using the example code above, the _only_ thing I can get it to return is a
fully completed symbol-name.
