192 be a letter. Gnus will call the function gnus-user-format-function-X,
193 where X is the letter following %u. The function will be passed a
194 single dummy parameter as argument. The function should return a
195 string, which will be inserted into the buffer just like information
196 from any other group specifier.
198 Note that this format specification is not always respected. For
199 reasons of efficiency, when listing killed groups, this specification
200 is ignored altogether. If the spec is changed considerably, your
201 output may end up looking strange when listing both alive and killed
204 If you use %o or %O, reading the active file will be slower and quite
205 a bit of extra memory will be used. %D and %F will also worsen
206 performance. Also note that if you change the format specification to
207 include any of these specs, you must probably re-start Gnus to see
