If that's the only problem with the doc string, then I already added a
note to that affect (although I wonder why a user who doesn't use 'ls'
would be bothered by this factoid).  FTR, it was very hard to
understand from the original report that this is the source of the
confusion.  Why would someone expect Emacs to check what 'ls' does if
'ls' is not used?

Anyway, I'm now closing this bug, as I don't think we have anything
else to do here.
