Andy McFadden 83da0d952c Fancy comments, part 1
Added a "fancy" flag to MultiLineComment.  If set, we will use
formatting commands embedded in the text itself.  The max width pop-up
and "boxed" flag will be ignored in favor of width and boxing
directives.  (See issue #111.)

The current "fancy" formatter is just a placeholder that folds lines
every 10 characters.

Removed FormattedMlcCache (added two changes back).  Caching the
rendered string list in the MLC itself is simpler and more efficient
than having a separate cache, and it works for Notes as well.

Added anchors for more comments in the 20090 test.
