A couple of troff questions.

1) the mm macro code request many diversions with the ' instead of
   the .  .  I know the basic diff, however is there some secret
   action that a 'di does? (e.g. something with breaks when the
   macro is read?)

2) the mm code has many escapes with multiple backslashes, and
   I know why, but in some case (like in one place threre are 8
   \'s), so the question is, is there some reasonable way to
   figure out how many backslashes are needed? Is a basic
   rule of one pair per prevented interpretation valid?

3) any reasons for nested diversions in the mm code?

This is not a quiz -- answers to these questions make you feel
better about mucking with mm source.

thanks in advance, rich
