Semantic detail (relevant in this context): `point' is always between
two characters, which is why there is no (char-of POS) but there are
(char-before POS) and (char-after POS).

Yes, we need to address those.  Making invisible front-sticky and
not rear-sticky (in the info buffer) is easy enough.

I guess the question now is: should we give preference to the desire
to ensure that "self-insert-command will insert a visible character"
or to "`char-after' is what the user sees (i.e. is visible)".
