Great! The Kharoshthi script is finally being included in Emacs!

Here are my two cents on the patches:

Should Kharoshthi be written with diacritics? I know Kharoṣṭhī is more correct way to write it, but other Indic scripts are written without it.

If this is a more correct way, should the others be changed as well?

Also I noticed that Kharoṣṭhī and Gāndhārī are written in IAST but not Saṃskṛta.

Also since now there is also a misc-lang.el in lisp/leim/quail/ I think the Kharoshthi input method should be moved there.

Thanks.
