I think it is allowable for raw results to include newlines.  After if R
returns a newline, the purpose of raw results is specifically to *not*
change the result.  I believe the best approach is to customize the
inline results wrap as above, and then use non-raw processed results
when inline results without newlines are desired.

Does this sound reasonable?
