I find the normal dired buffer a bit too busy but
dired-hide-details-mode a bit too lacking. So I'd like show only the
details I care most about, for instance like this:
--8<---------------cut here---------------start------------->8---
/home/augusto/emacs:
4.0K Feb 25 .
4.0K Feb 20 ..
4.0K Feb 25 admin
4.0K Feb 20 autom4te.cache
4.0K Feb 25 build-aux
3.6K Feb 20 aclocal.m4
11K Feb 25 autogen.sh
932 Jun 6 BUGS
...
--8<---------------cut here---------------end--------------->8---
The above can be obtained by setting
(setq dired-hide-details-preserved-columns '(5 6 7))
After writing this, I realized one could easily modify the new user
option to be an alist mapping column numbers to arbitrary text
properties to be applied to that column. If anyone thinks this variant
is useful, I'd be happy to adapt the patch.

Thanks, installed on the master branch. Feel free to post further
enhancements if you think they will be useful.

I was having second thoughts about this idea 😬. The feature is useful
but difficult to implement right.
The problem is that some columns of 'ls -l' are left aligned, so it's
impossible to know where a column starts or ends by looking at an
individual line.
I think I would rather revert the commit until someone comes up with a
better idea, if you don't mind. The ideal would be if 'ls --dired'
would report the names and positions of the columns.

I'm not sure I see a problem with counting columns.
What is the harm of keeping the commit on master? If we get
complaints about it, we have ample time to remove the feature when and
if we get those complaints.

The problem is that the code asssumes the columns are right-aligned,
which is not true for user and group. So for instance this listing:
drwx------. 43 augusto augusto 69632 Mar 4 12:21 .
drwxr-xr-x. 4 root root 4096 Aug 9 2022 ..
drwx------. 171 augusto augusto 12288 Feb 27 11:52 .cache
will get abridged like this:
69632 Mar 4 12:21 .
4096 Aug 9 2022 ..
12288 Feb 27 11:52 .cache
But if you don't mind that, we can keep the code and see if someone
finds a nice way to deal with it.

We could perhaps mention the caveat with right-aligned columns to the
doc string, and expect users to avoid those columns?
