Run manager? The BlockLayout?

That was my (somewhat muddled) point with the above reference to the
FWIW I've reimplemented the functionality from scratch with all the
decisions being made in the BlockLayout loop. An added bonus is that
it's quite a bit more efficient. I still have to sort out the EOL
case: I know what needs to be done, I just need to determine when to
do what, and my brain's nearing caffeine depletion real fast now, so
it'll have to wait till tomorrow.
Oh, and I'll document it to death, including listing (asserting) the
assumptions and what cases the code is expected to handle. If the
requirements for the function ever changes it should make it a bit
easier to adjust the code.
And a final point, Justin Bradford mentioned using invisible Runs to
enclose Runs of a field. That should also work with the new code since
it makes only a simple assumption about where to find Runs that can
contain the point (the assumption being that there must be at least
one such Run on a line).
Anyhu, having praised my code to death now, I'm sure Murphy will see
to a complete code (or harddisk) breakdown tomorrow, so this remains
vaporware until sometime tomorrow afternoon (CEST). Don't hold your
