2992 will be inserted into the summary just like information from any other
2995 The %U (status), %R (replied) and %z (zcore) specs have to be handled
2996 with care. For reasons of efficiency, Gnus will compute what column
2997 these characters will end up in, and \"hard-code\" that. This means that
2998 it is invalid to have these specs after a variable-length spec. Well,
2999 you might not be arrested, but your summary buffer will look strange,
3000 which is bad enough.
3002 The smart choice is to have these specs as far to the left as
3005 This restriction may disappear in later versions of Gnus.
3007 General format specifiers can also be used.
