The XSMP does not specify when the SmDiscardCommand will/should be
executed. For example, what if the user logs out, and only then unchecks
"Save this session for future use" or something? Geany will be
terminated without any notice, and the discarding remains to the SM. So
we'd better do both.

This is a rare situation, and the executable name can't be determined
100% reliably without using /proc or something (there is no such UNIX
API). You can try a few programs from the GNOME Official applications
list, and if they simply store argv[0], I think it'll be too much for
Geany to do more than that.
