11773	Saving osm files in JOSM will save the nodes in one of two orders	cmeeren@…	team	"==== What steps will reproduce the problem?
1. Open an OSM file in JOSM
2. Save the file without changing anything
3. Look at the file in a text editor (or make an md5 hash, or similar)
4. Re-save the file a couple of times (without restarting JOSM), observe in the text editor that nothing changes
5. Restart JOSM
6. Redo steps 1-5, observe significant changes in the OSM file
7. Redo steps 1-5 again, observe in the text editor that the file matches the 1st time you saved it
8. Redo steps 1-5 ad lib, observe that JOSM seems to change between two ""states"" every time the file is saved

==== What is the expected result?

Nothing should change when an osm file is saved without editing. The order of the nodes should be the same each time the file is saved.

==== What happens instead?

Everything is changed, seemingly between two states every other time JOSM is started. This makes it difficult to version-control the OSM files with e.g. git (workaround: restart JOSM and re-save the file again to bring it back to the ""node order"" you have versioned).

==== Please provide any additional information below. Attach a screenshot if possible.
