One part of the split info documentation for screen appears to be missing: when visiting the
info documentation in emacs (GNU emacs 23.4.1), emacs complains
"Can't find screen.info-6 or any compressed version of it"
An inspection of the local filesystem confirms that no screen.info-6, compressed or otherwise,
exists in the info documentation folder (/usr/share/info). Neither does "Installed files" in
synaptic list such a file in my "screen" install.
