Input file:

.ad l
left adjustment, .j = \n(.j
.br
.na
no adjustment, .j = \n(.j
.br
.ad
return to previous adjustment, .j = \n(.j

  shows:

left adjustment, .j = 0
no adjustment, .j = 0
return to previous adjustment, .j = 1

-.-

Two different states should not be identified with the same numeric
value.
