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