LMI		 3057%u User defined specifier. The next character in the format string should
3058 be a letter. Gnus will call the function gnus-user-format-function-X,
3059 where X is the letter following %u. The function will be passed the
3060 current header as argument. The function should return a string, which
3061 will be inserted into the summary just like information from any other
3062 summary specifier.
3063
eec82323
LMI		 3064The %U (status), %R (replied) and %z (zcore) specs have to be handled
3065with care. For reasons of efficiency, Gnus will compute what column
3066these characters will end up in, and \"hard-code\" that. This means that
65a32076 3067it is invalid to have these specs after a variable-length spec. Well,
eec82323
LMI		 3068you might not be arrested, but your summary buffer will look strange,
3069which is bad enough.
3070
23f87bed 3071The smart choice is to have these specs as far to the left as
eec82323
LMI		 3072possible.
