Thanks for answering "officially".

I would separate VERSE from CENTER and QUOTE, because the 2 last don't respect
the linebreaks. They're not "verbatim" (defined, for me and for now, by the
latter sentence).

Thanks. I can understand that this problem has been underspecified, hence the
unclearness of what's the right behavior to adopt for VERSE.

Though, I don't understand cases where we would like to preserve the
"verbatimness" of the linebreaks, but not of the lists, which is the case,
currently, for VERSE. Is there any useful use case for that?

For me, both should be supported together, whichever the environment, or none.

Thanks a lot. I'll try to play with those later (in the evening?).

For the emails, what environment would you advice me to use in general?  The
patched VERSE, or back to EXAMPLE (distinguished from RESULT, since Eric's
patch to wrap the Org results)?

Best regards,
