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