Re: "Final" version of tty child frames

I attach what I have done so far.  It only handles LR text so far and
affects only the special case where W is the selected window and there
is a child frame on its frame.

I also attach a file tty-child-frames.el to be loaded with emacs -Q -nw.
With C-l and M-l make one or two child frames.  In the normal frame do
M-x info and scroll it if necessary so you an see a line which extends
past one of these frames.  On such a line lean on C-f and C-b - the
cursor should remain invisible as long as point is hidden by a child
frame and should reappear as soon as it is no more hidden.

I won't dispute that the patch might be overly simplistic and probably
won't correctly handle properties like display strings in the hidden or
in the covering parts.  But what we want to handle here is a very
peculiar case and I think that an approximation like mine is better than
the present state of affairs.  And it can be easily removed as soon as a
working solution is found that allows to splice in any underlying frame
parts in the current matrix.
