196 %u User defined specifier. The next character in the format string should
197 be a letter. Gnus will call the function gnus-user-format-function-X,
198 where X is the letter following %u. The function will be passed a
199 single dummy parameter as argument. The function should return a
200 string, which will be inserted into the buffer just like information
201 from any other group specifier.
203 Note that this format specification is not always respected. For
204 reasons of efficiency, when listing killed groups, this specification
205 is ignored altogether. If the spec is changed considerably, your
206 output may end up looking strange when listing both alive and killed
209 If you use %o or %O, reading the active file will be slower and quite
210 a bit of extra memory will be used. %D and %F will also worsen
211 performance. Also note that if you change the format specification to
212 include any of these specs, you must probably re-start Gnus to see
215 General format specifiers can also be used.
