[tex-eplain] Correct format for \indexsee and \indexseealso

[Karl Berry]

    I think italic parentheses are ugly. 

Well, I agree.

    Even worse when the open and
    close parentheses don't match. 

True :).

    I'd prefer
       \def\indexseeword{see}%
       \def\indexsee#1#2{({\seevariant \indexseeword\/ }#1)}

Looks good.

    And shouldn't that italic correction be there?

Seems like it to me.

Dorai ... are you there?  Does this look ok?  And will you be able to
look at the question of the punctuation before the (?

Thanks,
