For Indian languages mr,gu,hi,te,kn,pa,or,ta,ml,bn do not have suffix rules and TRY sequences (http://sourceforge.net/p/hunspell/bugs/240/)
I have modified existing hunspell wordlists but due to its size i can't send it as patch
Modified wordlists are available on
https://gitorious.org/hunspell_dictionaries/hunspell_dictionaries/source/b3750ae0ee5b677449da80bfa33780c1ca8c1383:wordlists
This is about the individual dictionaries. hunspell itself doesn't bundle the individual dictionaries, so this isn't the right place for modifying those. Either there are no actual upstream for them, in which case you can just publicize those are the new upstream, or there are individual upstream projects for each language which might be interested in merging the changes.
