Exactly - I have the same opinion and I wrote it in the previous
email ... and as humans do differ and they could have different wishes
about format of output, I would expect something to tune output in ls -
without processing through awk/sed/whatever utilities.

I'm quite sure that you (and Jim) never needed that option. Otherwise it
would had been already implemented. In my case it is slightly different.
I never needed that option, but I sometimes wished to have it. For me
is ls -l too verbose and other ls formats too simple. I would like to
have something like with format "colored_name_with_link
(owner:group:filetype:octalmode) Human-readable_size" - so e.g.
bar (bar :root:-:0664) 24K
baz (baz :root:-:0664) 100K
bazlink -> ./baz (root:root:l:0777) 5
foo (foo :foo :-:0664) 10K
That would be enough for me in most cases (octal form is enough for me,
in most cases I don't need ACL char, number of links and mostly not even
the time). Now I have to parse things out of very verbose long format
(and every user has to parse it). Easy, but I wish to have another
choice - and this choice could be --user-format option.

You are right, it is a lot of interface for all users to parse. So
probably user-format description should be removed from --help
completely - and there should be only pointer that format is described
in info documentation.
