-stable review patch.  If anyone has any objections, please let us know.
---------------------

From: Samuel Thibault <samuel.thibault@ens-lyon.org>

VT notifier callbacks need to be aware of console switches.  This is already
partially done from console_callback(), but at that time fg_console, cursor
positions, etc.  are not yet updated and hence screen readers fetch the old
values.

This adds an update notify after all of the values are updated in
redraw_screen(vc, 1).
