I don't think whether we include the command for which the predicate
burped is important: either way is fine.  OTOH, it would be preferable
if a burping predicate wouldn't prevent the inclusion of other commands
in the completion list.  It's probably tolerable to just prevent
completion altogether in case of an error, but not to prevent
`M-x` altogether.
