Dataset too large on saved osm file

[nidi0]

It looks to me like a problem exist, if the following occurs:

1. Successfully download an area which is just below the API data limit
2. Wait some months / years until this area has accumulated more data
3. If you now want to update the data in the saved .osm file, you get an error (too much data).

The obvious workaround is to redownload.

JOSM might want to allow to split the areas of previously downloaded areas if they have become too large (data wise).
