I was composing a search by successively approximating the
desired result.  I filled in the query name field.  Every
time I searched it created a new query with the same name.
I think that (at least by default), reusing the same name
should cause any existing query with that name to be
overwritten by the new query.  Having multiple queries with
the same name makes little sense since you can't distinguish
one from another.
