I've tried this with a "method" trick, but that does not work too well
with 'location=intext'. Anyway, here is what I did:

\setuptyping[prog]
              [bodyfont=small,
               before={\begingroup\setuplinenumbering[style=small,%
                       step=2,start=3,location=inmargin,method=type]
                       \startframelisting \obeylines 

                       \startlinenumbering},
               after={\stoplinenumbering\stopframelisting\endgroup}]

Probably, but I do not know.

The setup obeys normal grouping rules (hence the \begingroup ...
\endgroup in the code above)

That should be possible in typing environments. I even think there was
a wiki page on that. But in non-verbatim environments, the breaking is
simply TeX's paragraph builder, and I do not think context allows
tinkering with that (I could be proven wrong, of course)
