Change 212
An interpretative integration of Peter Glasscock's -o file support.
This is handled in the make1() routine, rather than in all the
exec*.c files. -o x writes the actions to file x rather than
actually running them. Implies -n (but not -d2).

Tip: Use n and p to cycle through the changes.
