2653 (instead of after first colon).
2654 %u User defined specifier. The next character in the format string should
2655 be a letter. Gnus will call the function gnus-user-format-function-X,
2656 where X is the letter following %u. The function will be passed the
2657 current header as argument. The function should return a string, which
2658 will be inserted into the summary just like information from any other
2661 The %U (status), %R (replied) and %z (zcore) specs have to be handled
2662 with care. For reasons of efficiency, Gnus will compute what column
2663 these characters will end up in, and \"hard-code\" that. This means that
2664 it is invalid to have these specs after a variable-length spec. Well,
2665 you might not be arrested, but your summary buffer will look strange,
2666 which is bad enough.
2668 The smart choice is to have these specs as far to the left as
2671 This restriction may disappear in later versions of Gnus.
2673 General format specifiers can also be used.
