Wouldn't this change the behavior for people running old KDE which
doesn't have XDG_CURRENT_DESKTOP, giving "kdiff3" much lower priority
than it had before?

This change also illustrates why I wasn't convinced that patch 2/3 was
necessarily a good idea. When you touch 'cross_desktop_tools' here,
you end up having to touch all the other 'tools=' lines anyhow, so the
introduction of 'cross_desktop_tools' didn't buy much in terms of
reduced maintenance cost.

Yeah, true.. So to avoid this we can just also check for
KDE_FULL_SESSION, that has been introduced by KDE 3.2, and this should
be enough I think.

Yeah, I had the same feeling, TBH.

I'm not a user of git-mergetool or KDE, so I can't speak as an
end-user. My comment was made merely as a reviewer of the code.

If it is easy to avoid the behavior change by also checking
KDE_FULL_SESSION in addition to the new check of XDG_CURRENT_DESKTOP
without it being a maintenance burden, then that sounds like a good
choice. On the other hand, if there wasn't a good way to avoid
changing behavior for users of older KDE, then explaining that in the
commit message would be expected.
