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