I'm not sure whether this would warrant a more detailed approach.  For
one thing, there probably should be a minimum height of the brackets so
that they stay recognizable.  For another, I would sort-of expect that
an empty stencil is bracketed similarly to a point-stencil _except_ that
the padding between the brackets is used only once instead of twice.
Similarly for \hspace (use the given space plus _one_ padding).

That's what feels natural and useful to me, but of course, other
behaviors might also have a reasonable rationale.
