Re: [patch #3596] Sort directories before files in "ls"

[Alfred M\. Szmidt]

   ok, I'll keep it in mind when I'll redo the patch. I'll keep only
   the "--group-dirs" option and remove "-e".

--sort-directories-first is I think a clearer name, --group-dirs says
nothing about how the directories are group, if there are several
groups, etc.  If --sort-directories-first is to long,
--directories-first would be clearer.  And if that is still to long,
maybe a new keyword for --sort would do.

I think that abberviating directories to `dirs' is bad.
