LMI		 3014The %U (status), %R (replied) and %z (zcore) specs have to be handled
3015with care. For reasons of efficiency, Gnus will compute what column
3016these characters will end up in, and \"hard-code\" that. This means that
65a32076 3017it is invalid to have these specs after a variable-length spec. Well,
eec82323
LMI		 3018you might not be arrested, but your summary buffer will look strange,
3019which is bad enough.
3020
23f87bed 3021The smart choice is to have these specs as far to the left as
eec82323
LMI		 3022possible.
