recentf: not applying all filters

[Michael Mauger]

When `recentf-open-files-items' is non-nil (which it is, by default), then 
`recentf-open-files-items' does not apply the `recentf-menu-filter' filter.

Thus if you have recentf-mode enabled, and you select the "More..." entry on 
the menu, the resulting buffer of additional recently opened files, will not be 
properly sorted (or whatever filter behavior was requested).

Was this intentional?  Is there a conflicting behavior that this avoids?
