191 %F The disk space used by the articles fetched by both the cache and agent.
192 %u User defined specifier. The next character in the format string should
193 be a letter. Gnus will call the function gnus-user-format-function-X,
194 where X is the letter following %u. The function will be passed a
195 single dummy parameter as argument. The function should return a
196 string, which will be inserted into the buffer just like information
197 from any other group specifier.
199 Note that this format specification is not always respected. For
200 reasons of efficiency, when listing killed groups, this specification
201 is ignored altogether. If the spec is changed considerably, your
202 output may end up looking strange when listing both alive and killed
205 If you use %o or %O, reading the active file will be slower and quite
206 a bit of extra memory will be used. %D and %F will also worsen
207 performance. Also note that if you change the format specification to
208 include any of these specs, you must probably re-start Gnus to see
211 General format specifiers can also be used.
