I missed it.  There've been an awful lot of groff posts in my inbox
this past year. :)

Is that all it is, then? 'groff -ks' is invoking preconv before
soelim?  My confusion grows.  If soelim, invoked at the start of the
chain, renders the sourced file correctly, it suggests that soelim
is performing preconv magic on it.  Why, then, doesn't '-s' do the
same, regardless of preprocessing order?
