Something like a thin, dotted rectangle? Maybe even gray, as far as colors
are
possible?

The real question is:
* Should the size of an automatic right delimiter be dependant on its
adjacent
indices? Should this happen generally? Only for vertical bars? Or by some
optional switch?
or:
* Should the substitution-operator be a postfix-big-operator, conceptually
distinct from from a vertical-bar-right-delimiter big enough for indices and
behaving similar to the prefix-big-operators?

I have the feeling the second is overkill that won't be correctly understood
by most users.

The first, though, will probably only shift the problem to other cases that
will suddenly look strange.

Therefore, I would suggest leaving it as it is for the moment and document
the
trick somewhere. (Is there a section "assorted bits'n'pieces"?...)

When it comes to semantics, the correct thing to do in the long run would be,
to have opening and closing delimiter as parts of one entity containing
everything in between. The menu would then not contain single delimiters at
all, but a selection of common pairs (matching delimiters and pairs like
"left-invisible-delimiter <-> right-bar-delimiter") and an additional option
of custom-made-pairs. Typing a single opening delimiter would then
automatically create a matched pair, which should be correct behaviour in
99.9% of the cases. Of course, that's a major change - no idea whether it
would be worth the hassle?

Ciao,
Nobbi
