Your changes look good with my setup. Feel free to close this bug once
you commit these changes.

Do you see heart-shaped strcutures in that line much similar to what you
see in ta-itrans-1.png that I attached earlier? Then it means that the
display is malformed.

If you compare that line with the adjoining ones, then you will see that
the heart-shaped structure is a place-holder for the consonant symbol
and the "redundant" consonant symbol itself has to be removed.

I see. It wasn't clear to me that they were displaying alternative
keys. I think we can maintain status quo.

Ok.

I have this in .emacs.

(custom-set-variables
 '(pop-up-windows nil))

With the above setting, cursor always ends up in the tail of the buffer.

If I leave the above variable at it's factory value then the cursor ends
up in the head of the buffer. 

I consider this behaviour buggy. Should I open a separate bug for this?
