Thanks, I didn't know that.

WM_CLIENT_MACHINE(STRING) = "escher.home"

When I use xprop on my Emacs 23.1.91 build or on the Emacs 23.1 built by
openSUSE, I get

WM_CLIENT_MACHINE(STRING) = "escher"

On all three Emacsen system-name is "escher.home".  $HOST and $HOSTNAME
are "escher".  In /etc/hosts "escher.home" is the
Full-Qualified-Hostname and "escher" is the Short-Hostname.  So why is
WM_CLIENT_MACHINE the former instead of the latter on Emacs 24?
