This appears to work (from dev.20), and it looks like it doesn't really
complicate things any.
It goes on the assumption that COLLAPSE_BR_TAGS=TRUE means use the new
collapsing technique, and that COLLAPSE_BR_TAGS=FALSE means add a \r
for every <BR>, regardless of the number of them encountered. If someone
wants to take this and make it a troggle (like comment parsing: correct,
minimal, or historic), that would be even better.
