Sounds like the right idea.  Some questions:

   - Would it be possible for this to preserve indentation?
     Ie preserve leading white space on a line that is not entirely
     white-space ?
     Maybe the rule would be to replace with a single "\n",
     all white space up to and including "\n".
     Is this getting too complicated?

   - If the chomp option were made extensible, seems to me that the
     corresponding chomp flag would need to be extensible also.

   - (I'd suggest that just setting CHOMP to a string or regexp may be
     a bit ambiguous, but I suppose you were just using that as an
     illustration.)

Thanks,
