I don't know.  I have no idea who would use that option.  I presume
the vast majority leave the default nil setting of trash-directory
intact, and get the freedesktop style trash (and the Recycle Bin on
Windows).  I see no reason to have a feature that is useful for a tiny
minority of users, while the bulk of them need to use system tools
instead.  Besides, if trash-directory is a simple directory, do we
really need to tell users how to move files out of there?

Sorry, makes no sense to me.
