E-mail address forced to lower case in user ID?!?

[Rich Wales]

I noted today that the e-mail address portion of a user ID is always
forced to lower case.  (g10/keygen.c, function ask_user_id, line 611.)

If this is going to be done, it should really only be done for the
domain name (the part to the right of the "@" sign).  The user name
(left-hand side) in an e-mail address is explicitly allowed to be
case-sensitive in the Internet e-mail standard (RFC822, sec. 3.4.7).

As far as I'm aware, very few (if any) modern e-mail systems actually
care about upper vs. lower case in their own local user names.  But
since the standard permits case sensitivity, it seems to me inappro-
priate to force the left-hand side of the address to lower case when
constructing a key's user ID.
