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.
