Subject: Test for the macro "AT" fails

  The first test in
"groff/tmac/tests/an-old_AT_and_UC_footer_saved_and_restored.sh"
fails both with "groff/build/test-groff" and
"/usr/bin/groff (Debian GNU groff version 1.22.4)".

  The .AT and .UC macros must come after a page transition.

  These macros should give a warning
if they are called when no page transition has occurred,
something like:

.if \\n[nl]<=0 \{\
.  tm \\n[.F]:\\n[.c]: The macro \\$0 must be used later
.  tm in the input, e.g., after the text for the first .SH macro.
.\}


  This fact should also be documented in groff_man.7.man.
