I just committed a change to R-devel so that if debug is called on an
S3 generic function, all methods will also automatically have debug
turned on for them (if they are dispatched to from the generic).
I hope to be able to extend this to S4 and a few other cases that are
currently not being handled over the the next few weeks.
Please let me know if you have problems, or suggested improvements.
