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