[josm-dev] deleted new primitives

[Matthias Julius]

Ticket #4522 is about conflicts when merging new primitives that have
been deleted in one dataset.

I am wondering why do we keep deleted new primitives around in the
first place?  They are not stored on disk anyway.

The only reason I can think of is that it makes undo easier.  But, for
merging they should simply be ignored.

Any objections to that?
