bug#12158: 24.1; unclear, incomplete doc of window parameter `quit-restore'

If this is supposed to be internal, then do not doc it.  If not, please doc it
so readers can understand.

I only came to this doc because you pointed me to it explicitly, when trying to
investigate a (user) bug.  So it's not super clear (to me) just how internal
this topic should be.

> The window-pub branch contains a detailed description of an earlier
> version of this parameter.  You can find it here:
> http://bzr.savannah.gnu.org/lh/emacs/old-branches/window-pub/a
nnotate/head:/doc/lispref/windows.texi

The existence of that description outside of Emacs does not help users much.

> In the course of subsequent changes to the buffer display code, this
> description was omitted from the current version of the manual.

I guess you are saying that that omission was a mistake.  Please include the
missing info, then.

> These parameters are listed in this node in order to tell programmers
> that their names are in use and which parts of the Emacs code use it.
> If any information is missing, please provide a report.

It is not up to me to determine all that might be missing - I have no idea.  The
explanation should be be complete and understandable; that's all.
