You can also take a look at mpc.el
(bzr co http://www.iro.umontreal.ca/~monnier/bzr/mpc) where I do it with
align-to as well.  I "try" to handle right alignment, but in a very
naive way.  I don't think we can currently do it right in Elisp, because
there is a lot of missing information.  I could imagine getting it to
work, with a lot of effort based on forcing redisplay and using
posn-at-point to measure the display size of particular pieces of text.
But it's likely to be too slow to be practical.
