group parameter : display

[Julien Cubizolles <j.cubizolles@free.fr>]

I have two questions about the "display" group parameter.

From info: 

,----
| display
| Elements that look like (display . MODE) say which articles to display on entering the group. Valid values are:
| all
| Display all articles, both read and unread.
| an integer
| Display the last integer articles in the group. This is the same as entering the group with C-u integer.
| default
| Display the default visible articles, which normally includes unread and ticked articles.
| an array
| Display articles that satisfy a predicate.
| Here are some examples:
| 
| [unread]
| Display only unread articles.
| [not expire]
| Display everything except expirable articles.
| [and (not reply) (not expire)]
| Display everything except expirable and articles you've already responded to.
| The available operators are not, and and or. Predicates include tick, unsend, undownload, unread, dormant, expire, reply, killed, bookmark, score, save, cache, forward, unseen and recent.
`----


 * What articles does the "recent" predicate match ?

 * I can't get the "array" mode to work. When I set it to 
,----
| (display . [and (tick) (dormant) (recent)])
`----

or even 

,----
|  (display . [and (tick) (dormant)]) 
`----

gnus asks for the number of articles to display upon entering.
