completion-styles does not influence the set of completions and the
completion field (which is what lisp-completion-at-point returns).
Instead it influences how the completion UI acts on that information.

I.e. the value of completion-styles is only used when completion is
actually performed (e.g. by completion-in-region).

A space should not be needed when the subsequent char is an open-paren.
