2991 be a letter. Gnus will call the function gnus-user-format-function-X,

2993 current header as argument. The function should return a string, which
2994 will be inserted into the summary just like information from any other
2997 The %U (status), %R (replied) and %z (zcore) specs have to be handled
2998 with care. For reasons of efficiency, Gnus will compute what column
2999 these characters will end up in, and \"hard-code\" that. This means that
3000 it is invalid to have these specs after a variable-length spec. Well,
3001 you might not be arrested, but your summary buffer will look strange,
3002 which is bad enough.
3004 The smart choice is to have these specs as far to the left as
3007 This restriction may disappear in later versions of Gnus.
3009 General format specifiers can also be used.
