That would mean it has the same sense as HUP, which is logical.

I can't see anything in the Single UNIX Specification, anyway.  The nohup
description refers to the sh description, but doesn't seem to specify it
one way or another.

By the way, looking at the standard, I discovered the following are
supposed to work.

% echo $(
echo # a comment)
)
% echo $(
cat <<\eof
a here doc with )
eof
)

That would basically mean recursively parsing the $(...) straight away,
which could be quite a lot of work.  I'm delighted to find it doesn't work
with HPUX 10.20's POSIX sh, either.
