Message #5 received at submit <at> emacsbugs.donarmstrong.com (full text, mbox):
`dired-guess-default' returns a list of default shell commands
appropriate for its input, FILES. It should remove duplicates from
this list before returning it.
Also, the doc string is:
"Guess a shell commands for FILES. Return command or list of commands.
See `dired-guess-shell-alist-user'."
This is not correct grammatically. Suggestion:
"Return a shell command, or a list of such, appropriate for FILES.
See `dired-guess-shell-alist-user'."
BTW (I didn't check the code - just a naive question): Why do we
return sometimes a single command instead of a singleton list of that
command? What is gained by this added complexity? Is there some
calling code that *must* receive a command and not a list of commands?
It seems like any calling code would need to be able to handle the
list case, including a singleton list, anyway.

Ok; done.

I've changed it to something like that.

I'm guessing somebody extended the function at some point.
