I don't know how portable #ls -ld" really is.

The parts with mode bits, nlinks, uid, gid, size, and date part do
have some variations.  For example, we have been burned on ACL
enabled systems having some funny suffix after the usual mode bits
stuff.

However, as far as this test is concerned, I do not think "how
portable is the output from ls -ld" is an especially relevant
question.  None of the things we expect early in the output (the
fields I enumerated in the previous paragraph) would contain " -> ".
And we know that we do not use a filename that has " -> " (or "->")
as a substring in our tests.

We don't have to use readlink, even on platforms where we do have
readlink.  Building the conditional to be checked at runtime and
providing a shell function read_link that uses "ls -ld | sed" or
"readlink" depending on the runtime check is wasteful.

Just a short, curious question: Is this patch to be accepted/included some time?
I didn't see it in 2.8.4 nor 2.9.0. Maybe it just fell off the table...

Yes, I think this fell off the table as I was waiting for some kind
of agreement or counter-proposal, neither of which came and the
thread was forgotten.

Unless Torsten still has strong objections (or better yet, a better
implementation), I am inclined to queue it as-is.

I just double-checked the man pages for Mac OS and opengroup:
No better implementation from my side -> No objections
