The slow display should only happen when the list is really long,
i.e. basically if you hit TAB with an empty minibuffer.  So we could
indeed easily use a different completion behavior in this case.

You mean show the list as a tree?  That cannot be done with the current
default completio code.  But some variant of it can be done.  E.g.  we
can use a completion similar to file names, so additionally to
<charname> we could accept input of the form <category>/<charname> and
provide completion on this (and if the completion list on <charname> is too
long, don't display it: only display the completion on
<category>/<charname>).
