It sounds like this would just as easily be accomplished with a way to
search for all messages that don't have any tags.  I don't think there's
a way to do that at the moment.  Carl (on #notmuch) just confirmed that
this can only be accomplished by construction the search explicitly.
Here's what I came up with:

search=$(printf 'not (%s)\n' "$(notmuch search --output=tags '*' | xargs -I'{}' echo tag:'{}' | tr '\n' ' ' | sed 's/ $//' | sed 's/ / or /g')")
notmuch search "$search"

Someone can probably figure out how to simplify that a bit.  I don't
think there's an easy way to save a search that's generated on the fly
like that.  Some elisp magic is probably in order.

jamie.
