This is because AT is now a macro.  From the groff(7) manpage:

: Strings share their name space with macros.  So strings and macros
: without arguments are roughly equivalent; it is possible to call a
: string like a macro and vice-versa, but this often leads to unpre-
: dictable results.  The following strings are predefined in groff.

Werner,

Would it make sense to rewrite ``.de1 AT'' as ``.if !d AT .de1 AT'',
and similarly for .UC?

Also, .AT and .UC are of historical interest only; would you still
like we document them in the manpage?  If so, should they be briefly
documented, or in full-depth details?
