2949 will be inserted into the summary just like information from any other
2952 The %U (status), %R (replied) and %z (zcore) specs have to be handled
2953 with care. For reasons of efficiency, Gnus will compute what column
2954 these characters will end up in, and \"hard-code\" that. This means that
2955 it is invalid to have these specs after a variable-length spec. Well,
2956 you might not be arrested, but your summary buffer will look strange,
2957 which is bad enough.
2959 The smart choice is to have these specs as far to the left as
2962 This restriction may disappear in later versions of Gnus.
