I want to see what the group thinks of this idea...
Instead of having to code /free and /end-free, to drop into free form
and back out again, why not just let the compiler make the decision, on
a line-by-line basis, depending on the presence of the "C" in the column
(for C-specs)? If the "C" is there, treat the line as fixed format. If
there is a blank in that column, then we are in /free format.
