I suppose it was mostly the work I did to make command substitution parsing
call the bison parser recursively instead of using the ad-hoc scheme that
had been in place for years.

Once you identify all the relevant parser state, the alternate nofork
command substitution becomes easier.

Time and motivation are always factors, of course.
