"speck" was an attempt to solve this and a couple of other problems I
encountered with flyspell.  I didn't do any serious work on this for
more than a year, hence something might have broken in the meantime.
Also, full support for Ispell was never finished, Aspell support is more
reliable, IIRC.  If you nevertheless want to give it a try - comments
very appreciated ;-)
