2700 %* If present, indicates desired cursor position
2701 (instead of after first colon).
2702 %u User defined specifier. The next character in the format string should
2703 be a letter. Gnus will call the function gnus-user-format-function-X,
2704 where X is the letter following %u. The function will be passed the
2705 current header as argument. The function should return a string, which
2706 will be inserted into the summary just like information from any other
2709 The %U (status), %R (replied) and %z (zcore) specs have to be handled
2710 with care. For reasons of efficiency, Gnus will compute what column
2711 these characters will end up in, and \"hard-code\" that. This means that
2712 it is invalid to have these specs after a variable-length spec. Well,
2713 you might not be arrested, but your summary buffer will look strange,
2714 which is bad enough.
2716 The smart choice is to have these specs as far to the left as
2719 This restriction may disappear in later versions of Gnus.
2721 General format specifiers can also be used.
