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