Details:

When using C-a : "windowlist -g" in one pane of a screen session and then
changing active windows in another pane, the displayed list of windows in the
first pane are initially sorted by window number as expected; however, the
list is reordered such that windows selected in the second pane are bubbled up
to the top of the list, as if maintaining a most recently used order (even
bringing nested windows outside of their associated groups in doing so).  The
window list should not be reordered in this case, since the expected order is
by window numbers and the window numbers are not changing.

Using C-a : "windowlist -g -m" works as expected; windows and window groups
with the same parent are sorted with respect to each other in MRU order, and
the list is updated correctly when different windows become the most recently
used.  It's possible that some of the code that reorders windows in a
windowlist command is being executed erroneously when the -g flag is specified
but the -m flag is not.

This bug was produced in Screen 4.1.0 on Cygwin.  Attached is the .screenrc
environment used in producing this bug.
