193 %E Icon as defined by `gnus-group-icon-list'.
194 %F The disk space used by the articles fetched by both the cache and agent.
195 %u User defined specifier. The next character in the format string should
196 be a letter. Gnus will call the function gnus-user-format-function-X,
197 where X is the letter following %u. The function will be passed a
198 single dummy parameter as argument. The function should return a
199 string, which will be inserted into the buffer just like information
200 from any other group specifier.
202 Note that this format specification is not always respected. For
203 reasons of efficiency, when listing killed groups, this specification
204 is ignored altogether. If the spec is changed considerably, your
205 output may end up looking strange when listing both alive and killed
206 groups.
208 If you use %o or %O, reading the active file will be slower and quite
209 a bit of extra memory will be used. %D and %F will also worsen
210 performance. Also note that if you change the format specification to
211 include any of these specs, you must probably re-start Gnus to see
212 them go into effect.
214 General format specifiers can also be used.
