Well, the problem is that adjust only exists on some AT&T Unices.

Some of us use a BSDish flavour of Un*x and we use fmt(1), e.g.

{!}fmt -72		# actually, 72 is the default, so just {!}fmt suffices

fmt      the name of the utility
-72      sets the right margin to 72.  All line wrapping is done automatically.

I guess you meant to say "Use control-V control-M to get a return in the map:"

map ^A  {!}fmt -72 ^V^M


For some reason, this thread had the title

>> VI: Positioning the cursor ("|") from within a macro doesn't work.

Which is an odd thing to say, since "|" works OK from within a macro,
provided you quote it with two control-V's, e.g. typing

:map v 73^V^V|F r^V^M

gets you a macro that breaks the line at the last space before column 73.
Not that you need such a macro if your system has either adjust(1) or fmt(1).
