A really good question. Let's think about parse_user()... If t does not
include brackets the string ends up in name. If it does include brackets the
address ends up in email, including the brackets. So does (mode == 2 && *p ==
'\n') ever get true? Probably we have a piece of dead code.

I think email always includes brackets or is NULL. In later case
cgit_get_gravatar() is not executed, so everything should be fine.
