[Bug 2154042] Re: ls: files are not sorted in alphabetical order by default

[Harm van Bakel]

Yes you're right, I can only reproduce the sorting issue with --group-
directories-first. I thought I had seen the same issue without it but I
can't reproduce it anymore. I probably got confused by all the different
combinations I tried. I will update the bug title.

** Summary changed:

- ls: files are not sorted in alphabetical order by default
+ ls: files are not sorted in alphabetical order when using --group-directories-first

** Description changed:

  Since upgrading from Noble 24.04 to Resolute 26.04, files and folders
- are not sorted in proper alphabetical order when running ls in Ptyxis.
- The sort order appears roughly alphabetical but with many exceptions,
- and there is no obvious pattern to explain the deviations. Casing does
- not appear to be a factor either.

- I tried switching locales but all of the following give incorrect sort
- results:

  Switching to gnuls restores proper alphabetical sorting.
