minimise "change area" bounding box so that local changes can be spotted easier

[RicoZ]

currently some 50-90% of OSM changesets indicate an area that is so large that watching local changes is completely useless.

As an example, this ​http://www.openstreetmap.org/browse/changeset/18754395 innocent change somehow spans half the earth even though the changes are local to a few hundreds meters.

It would be very helpful if JOSM could upload the changeset with a meaningful bounding box.

The bounding box is computed by the API, not by JOSM, see ​http://wiki.openstreetmap.org/wiki/API_v0.6#Bounding_box_computation.

Moreover, it is not an innocent changeset at all. If you try to download it:

​http://api.openstreetmap.org/api/0.6/changeset/18754395/download

You will see data in Germany and North Africa... The bounding box is perfectly correct, even if it's probably an error from the uploader.

you are right, I was relying on the OSM history viewer which makes it really easy to miss the African part of the edit.
