In https://issues.guix.gnu.org/58070#25 , I made the case that
Visuwesh's implementation does not have enough information to work
consistently. So, I thought the matter was settled. But sure, let's wait
for Visuwesh to chime in.

The indian.el file is likely to get very crowded in the future. But
sure, I'll move tamil99 into indian.el. Patch follows in a separate mail
soon.
