'A' vs blindfold

Fix an inconsistency with blindfold removal, eliminating possibility
of a panic (3.6.0) or an impossible (since mid-December, 2016).  The
'A' command treated blindfold removal as a multi-turn operation, the
rest of the wear/unwear code as single-turn operation so didn't try
to guard against it being disrupted.
