I'm not sure of the original motivation; but I guess that if it has
been there for thirty years it is now considered as the standard
interface by a few users.

In any case, even if we decide to change that, consistency would be
good, at least for CLI; the same policy for casing should apply in all
cases of completion.

Documenting it in the user manual would be good indeed; I'm not sure
where the proper place would be though.
