I currently don't have enough time to really evaluate the differences
between our layouts however, my layout can lead to really unexpected
results in certain cases and it is not tested well enough.  So I would
prefer for Arun's patch to go in.

One comment: why not use link to the Tamil99 keyboard layout spec [1]
and change "vowel+consonant after mellinam-vallinam consonant" to say
"vowel+consonant after hard-soft consonant" like it says in the spec to
help future maintainers who will read this code?

I don't think it is too crowded, FWIW.  The input methods are sectioned
off based on the language.
