Thanks, and sorry for forgetting about that.  (But in rereading the doc
string now, it seems either ambiguously worded or even wrong:

"Completion ignores file names ending in any string in this list.
It does not ignore them if all possible completions end in one of
^^^^^^^^^^^^^^^^^^^^^^^
these strings or when displaying a list of completions.
                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
It ignores directory names if they match any string in this list which
ends in a slash."

This seems to be saying that the *Completions* buffer should display the
file names libthread_db-1.0.so and libthread_db.so in the above
scenarios, but that is not what happens.  Or am I misconstruing the doc
string?  If so, perhaps it can be rephrased more clearly.

Thanks (again) for setting me straight.
