Okay, I understand. Yes, in my patch the strings returned by
'completion-filter-completions' must not be mutated by the API consumer
directly. This should be documented clearly, but it is not unexpected.
For example the API 'all-completions' which one can use to obtain the
strings from a completion table also requires the caller to not mutate
the returned strings.
