Digging into the community's lore with lei

I thought "that's odd", and, indeed, nq: is "nonquoted text". You want "q" for the opposite.

(This alone is enough of a reason to try lei. All the other search features? Oh I'm sucking all my email into this thing. I wonder how hard it is to teach notmuch the same search features? Or, hell, to have them share the same index? It's all Xapian, after all.)
