Subject: 31797: to match documentation, avoid expanding history when there is
 neither a word nor an event designator

There are still a few cases where expansion is attempted even though the
documentation indicates it will not be, but in most of those cases the
expansion will fail.  The now-fixed case would fall back to default
expansion of the previous command.
