Texinfo 4.0: @sc in menus

[Eli Zaretskii]

Try to use @sc{} in a menu, and "makeinfo --no-headers" will output a
bogus warning about all-uppercase argument.  Here's a patch:

1999-10-15  Eli Zaretskii  <[EMAIL PROTECTED]>

        * makeinfo/cmds.c (cm_sc): Don't print the warning about
        all-uppercase argument in menus under --no-headers.
