I don't think i understand your suggestion.  that value *is* used, by
the "(when show-button …)" construct later in the code.

The idea was to make the button shown by default, unless it was disabled
further down in the patch (in the "t" clause of the main "cond"
construct in notmuch-crypto-insert-sigstatus-button, which only triggers
if we legitimately don't have any status information (if "status" is
nil)).

So no, i think it's supposed to start off "t" and then get disabled in
the specific condition this patch tests for.

If i've misunderstood the e-lisp (entirely possible!) i would be happy
to be corrected.
