Actually that indent/noindent for the first line of the displayed
material was just a personal test to see if I could make it work
(so as to distinguish when the displayed material started a new
paragraph and when not --when there is indentation on the first
line it's because it starts a new paragraph ...)

Anyway, I built a "quick and dirty" patch which seems to work for
most environments which, I think, require it: itemgroups,
definitions, formulas, verbatim. You can put it in your cont-loc
between \unprotect ... \protect pairs:

=== END PATCH ===

Remember to issue the following instructions:

\setupformulas[indentnext=auto]
\setupitemgroups[indentnext=auto]

to make it work. No need to regenerate the formats (you may need
to refresh the filename database if you didn't have a cont-loc.tex
before that). Hans, can we hope for this to go into the core for
the next beta?

Note: while I think it should be done for quotations as well, this
seems to be a feature "in development" so I won't touch it for
now.
