Windows: the instances are stopped one by one. The last one wins.
X11: the session management supports instances.

It has a complete sm for the current single-instance behaviour, and an
incomplete multi-instance sm for the non-implemented multi-instance
behaviour. So the real question is, do we plan to introduce any multi
instancing in Geany in the foreseeable future? If not, the last
single-instance sm applies against 5530, and is quite stable.

The same answer as for a. and b.

Both Windows and X11-sm will ask you for any modified files.

(In the current implementation, both simply terminate.)
