hm, but it's not the writer who's in charge here, but the designer; so, in 
terms of intentional coding, one should code in such a way that whatever 
strange thing happens along the road (accidental empty line or not) the 
output is consistent. So, an in-par something should be coded as such so 
that the environment can handle it, as good as possible.

there are options for that -)

ah, so we should look ahead, doable but never 100% robust; with regards to 
looking back, definitely less robust

or a

text\par text, or

text\whow[expanding into \par]text

you can bet on that

such a feature should be tested for *each* environment with all kind of 
combinations, since spacing can really become nasty

hm, not sure it it hooks/should hook into start/stop

depends, this is not something that will be there in-a-minute, and i 
definitely don't want to break compatibility for a convenience over coding 
feature -)

The first thing is a proper \start/stopdisplay pair, so let's start with 
that; one can then hook that into start/stop an dlater we can see if some 
kind of auto-display is possible [display=none|before|after|both] or so
