Isn't it the other way around: Windows wants 'always' (except when it
doesn't, see below), while others want 'auto'?

As to when you won't want 'always': it's when Grep is invoked as part
pf a pipeline, where it's not the last part, or when the Lisp program
that invokes it wants to interpret the results, as opposed to showing
them to the user.
