206 be a letter. Gnus will call the function gnus-user-format-function-X,
207 where X is the letter following %u. The function will be passed a
208 single dummy parameter as argument. The function should return a
209 string, which will be inserted into the buffer just like information
210 from any other group specifier.
212 Note that this format specification is not always respected. For
213 reasons of efficiency, when listing killed groups, this specification
214 is ignored altogether. If the spec is changed considerably, your
215 output may end up looking strange when listing both alive and killed
218 If you use %o or %O, reading the active file will be slower and quite
219 a bit of extra memory will be used. %D and %F will also worsen
220 performance. Also note that if you change the format specification to
221 include any of these specs, you must probably re-start Gnus to see
224 General format specifiers can also be used.
