Any config can work at any scope. These are really just recommendations
on where the user might want to write a value. So I think it would be
fine to treat UNKNOWN as "just suggest the default location for
writing", as we do now.

TBH, I am not really sure what the criteria are for suggesting one
advice option as --global or not. I'd think most of them are about
squelching advice that the user already knows about, and thus they would
go into --global. I didn't really follow the earlier discussion that led
up to this patch, though.
