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