2763 %u User defined specifier. The next character in the format string should
2764 be a letter. Gnus will call the function gnus-user-format-function-X,
2765 where X is the letter following %u. The function will be passed the
2766 current header as argument. The function should return a string, which
2767 will be inserted into the summary just like information from any other
2770 The %U (status), %R (replied) and %z (zcore) specs have to be handled
2771 with care. For reasons of efficiency, Gnus will compute what column
2772 these characters will end up in, and \"hard-code\" that. This means that
2773 it is invalid to have these specs after a variable-length spec. Well,
2774 you might not be arrested, but your summary buffer will look strange,
2775 which is bad enough.
2777 The smart choice is to have these specs as far to the left as
2780 This restriction may disappear in later versions of Gnus.
2782 General format specifiers can also be used.
