Thanks a lot for reporting and for the explanation. I did not follow
Sanskrit pattern changes and I did not try to explore what these
characters are and what purpose they serve, I just accepted the patch
(http://tug.org/svn/texhyphen?view=rev&revision=276).

Next time I need to remember to try tests/make-formats.sh first before
accepting any patch :)

If someone could double-check that the changes are OK, I can submit
them to CTAN.

One more question: in the patched file there's no "zerohyph.tex"
loading. What difference does that make if any? I know that loading
sanskrit patterns makes no sense in pdftex, but we have a few more
languages that do the same.

Thanks,
    Mojca
