[Tagging] Sorting waterway relations?

[Joseph Eisenberg]

JOSM doesn't change seem to change the order when it sorts, if the
relation is already listed "backwards" but in an ordered string. It
also won't sort a waterway relation which includes sidestream members,
or gaps.

But if you sort an unsorted waterway and each of the ways can be put
into one line, it does generally put the arrows pointing down (the
upstream way is first, downstream last).
