161 where X is the letter following %u. The function will be passed the

176 a bit of extra memory will be used. %D will also worsen performance.
|

177 Also note that if you change the format specification to include any
|

178 of these specs, you must probably re-start Gnus to see them go into

319 evaluated. The content of the face field after the first true form is
