Log Message:
Use \n(dn to test whether the quoting diversion is empty, rather than
comparing the input line number.  The latter fails with things like:
.Oc Oc
because there is nothing in the diversion when the second Oc is executed,
which caused the command that adds \*(b2 to the output to be eaten.
