I don't think so.  It would be to support something that isn't in
usual messages.  And wouldn't even be necessary with "Nag: 1" or
whatever, if Norm is willing to update all of his existing Nag
messages.

A quick and dirty test for the empty Nag might be something like
this, with GNU grep:

    egrep --max-count=1 '^(Nag:|)$' | grep Nag:

No doubt others could come up with a more efficient test.
