Perhaps there are clever ways to figure it out. I say there are too many
dynamics and "fixes" in the code to get cdlatex-environment to work
already. Just consider this example where | is cursor
- foo | bar
Midway through, when ENV is reinserted, but before indentation the
end-marker will be *after* bar which is a line after \end{ENV}... I think
playing the "deterministic" card is non-trivial to get right in all cases
and org-cdlatex-environment-indent is already longer than
cdlatex-environment.

I don't see why not, but OK... Anyway it reminded me that I missed
"re-implementing" one feature of cdlatex, namely moving the cursor to the
right place. I refind this place do it by inserting a funny string and
replacing it. A poor man's marker, I guess...
