OK, but I'm not sure what you mean by "it" (please see below).

Sorry, I've lost context.  Which patch do you prefer and why?

I already installed the _AS_LINENO_WORKS patch
since you indicated that you liked it in
This patch is needed even if we get rid of the Awk+Sed code entirely.

As you mentioned, the patch that Raja R Harinath proposed in
is inadequate, as it can exceed sed limitations.

But the latest patch that I proposed, namely
doesn't have this problem: it uses two small sed scripts.  Also, it
fixes some other LINENO bugs that we've already discussed
(e.g. $LINENOUGH, $LINENO $LINENO).  When you say "This fix is wrong"
it suggests that you don't like this latest patch, but I don't know
why that would be.

I'm not worried about the Awk+Sed code anymore, as I don't think it
will ever be executed on any host of concern to the GNU project.
(Perhaps I shouldn't have tried to fix it, as that just seems to be
leading to confusion.  :-)

No argument there....
