I think the best way to do this is to do the following:
0) Ask for any other ideas as to where the regexp wouldn't work.
1) Write the function, and take care of the make-COMMAND-markup rule.
2) Use the new function to write convert-ly rules
3) Look for any errors caused by the use of the convert-ly rules being
applied
4) When the errors show up, do what is necessary to fix them.
Thanks,
Carl
