no. Except perhaps no the part about shipping both mime-types in one file.

Ah, in fact I had missed that part. Sounds more sane, now that I understand 
that.

So probably the cleanest solution would be having them added to R... Oh well.

I'm still somewhat worried about future clashes. _If_ R ever decides to start 
shipping these mime-types, RKWard is going to get the blame for conflicting 
names, I'm afraid. That's why my first thought was naming it rkward.xml 
(similar to libreoffice.xml, which also declares .xls, for instance). But no, 
I'm not sure.

Ok, will add.

I changed that a bit, and yes, it might be buggy, but I think you should find, 
the behavior is now:
- If a workspace has just been loaded, and not been touched, don't ask whether 
to save it before quitting / replacing it.
- If you touch some object in between, you should be prompted, again.
- Now as to why you're prompted for the initial - probably empty - workspace: 
It's that .Random.seed that gets created some time in the middle of starting 
up. Did not think up a nice way to cope with that, yet.

True.

Really?
