164 be a letter. Gnus will call the function gnus-user-format-function-X,
165 where X is the letter following %u. The function will be passed the
166 current header as argument. The function should return a string, which

174 reasons of efficiency, when listing killed groups, this specification
175 is ignored altogether. If the spec is changed considerably, your
176 output may end up looking strange when listing both alive and killed
179 If you use %o or %O, reading the active file will be slower and quite
180 a bit of extra memory will be used. %D will also worsen performance.
