top: enable other filtering via inclusion or exclusion

This change represents the extension of user filtering
based on inclusion or exclusion. However where 'U'/'u'
filtering provides an either/or choice, this extension
offers multiple choices applicable to multiple fields.

The 'inclusion' and 'exclusion' criteria can be freely
combined making a powerful tool to fine tune a display
and avoid clutter associated with uninteresting tasks.

I'm convinced it offers unimagined future flexibility!

(everything is perfectly justified plus right margins)
(are completely filled, but of course it must be luck)
