2995 will be inserted into the summary just like information from any other
2998 The %U (status), %R (replied) and %z (zcore) specs have to be handled
2999 with care. For reasons of efficiency, Gnus will compute what column
3000 these characters will end up in, and \"hard-code\" that. This means that
3001 it is invalid to have these specs after a variable-length spec. Well,
3002 you might not be arrested, but your summary buffer will look strange,
3003 which is bad enough.
3005 The smart choice is to have these specs as far to the left as
3008 This restriction may disappear in later versions of Gnus.
3010 General format specifiers can also be used.
