2907 current header as argument. The function should return a string, which
2908 will be inserted into the summary just like information from any other
2911 The %U (status), %R (replied) and %z (zcore) specs have to be handled
2912 with care. For reasons of efficiency, Gnus will compute what column
2913 these characters will end up in, and \"hard-code\" that. This means that
2914 it is invalid to have these specs after a variable-length spec. Well,
2915 you might not be arrested, but your summary buffer will look strange,
2916 which is bad enough.
2918 The smart choice is to have these specs as far to the left as
2921 This restriction may disappear in later versions of Gnus.
2923 General format specifiers can also be used.
