Details:

When I try to preselect a window in which a command should be executed, the
setting is (almost) ignored and the currently selected window is used instead.
This issue can easily be reproduced:

screen -dmS test -t win1
screen -r test -X screen -t win2
screen -r test -p 0 -X exec echo text0
screen -r test -p 1 -X exec echo text1

Now reconnect with

screen -r test

and see that text0 and text1 are printed in the same window. However, when
using a too high number (e. g. 2) for the preselection, the command is not
executed at all (which is good). I think the wrong preselection is not
intended, since with the following command the preselection works as
expected:

screen -dmS test -t win1
screen -r test -X screen -t win2
screen -r test -p 0 -X stuff $'echo text0\r'
screen -r test -p 1 -X stuff $'echo text1\r'


This was tested on Debian Jessie with Screen version 4.02.01 and on Rocks 6.1
with Screen version 4.00.03.

This issue might be related to Bug 31247
<https://savannah.gnu.org/bugs/?31247>. It might also be related that the
select command does not work (from outside):

screen -r test -X select 0
