Both are optional so far (completing multiple items in general and
completing multiple face names).

In Dired, after selecting several files, you can run a command once on all
of them when the command contains `*' surrounded by whitespace, and run for
each file when the command doesn't contain it.

In crm, we could use different separators, e.g. to use `,' to call the
action on all completion candidates, and to use `;' as a separator to call
the action on each of them.
