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