Looks good.
It's still not doing the old-ascii column dividers but to be honest
I'm not sure what the intended behaviour of old-ascii is. I've noticed
old-ascii only displays the line markers for dividing lines, not the
final one. That seems pretty useless and maybe it's why we switched to
the new "ascii" mode, I don't recall.
This is the way old-ascii displays when two columns are wrapping -- it
seems pretty confused to me. The headers are displaying newline
markers from the ascii style instead of : indicators in the dividing
line. The : and ; markers are only displayed for the first column, not
the second one.
Maybe since the : and ; markers aren't shown for the final column that
means the expanded mode doesn't have to do anything since the column
is only ever the final column.
