That patch looks ok, the infinite loop doesn't occur anymore and a quick
test with a file containing
ax
ay
az
now shows similar behaviour of /a and ?a  wrt. wrapping from top to bottom:
localhost:[ed-0.6] >./ed ~/test
9
.
az
/a
ax
/a
ay
/a
az
/a
ax
.
ax
q
localhost:[ed-0.6] >./ed ~/test
9
.
az
?a
ay
?a
ax
?a
az
?a
ay
.
ay

Without the patch az was skipped after jumping from top to EOF:
localhost:[ed-0.6] >./ed ~/test
9
.
az
?a
ay
?a
ax
?a
ay      <---
?a
ax

 Thanks!
