3002 %u User defined specifier. The next character in the
3003 format string should be a letter. Gnus will call the
3004 function gnus-user-format-function-X, where X is the
3005 letter following %u. The function will be passed the
3006 current header as argument. The function should
3007 return a string, which will be inserted into the
3008 summary just like information from any other summary
3009 specifier.
3010 &user-date; Age sensitive date format. Various date format is
3011 defined in `gnus-user-date-format-alist'.
3014 The %U (status), %R (replied) and %z (zcore) specs have to be handled
3015 with care. For reasons of efficiency, Gnus will compute what column
3016 these characters will end up in, and \"hard-code\" that. This means that
3017 it is invalid to have these specs after a variable-length spec. Well,
3018 you might not be arrested, but your summary buffer will look strange,
3019 which is bad enough.
3021 The smart choice is to have these specs as far to the left as
3022 possible.
3024 This restriction may disappear in later versions of Gnus.
3026 General format specifiers can also be used.
