The problem is very similar to bug 1095661, but the regression occurs when
going from openSUSE Leap 15.0 to 15.1.


Everything is working as expected in Leap 15.0 (with or without screen).
In Leap 15.1 only the setup without screen is working.


Inside screen I get this output:
--- snip ---
user@box:~> lsb-release -d
Description:    openSUSE Leap 15.1
user@box:~> echo $TERM
screen.xterm-256color
--- snip ---


How to reproduce
----------------
 - Start screen from the command line (tested with Konsole)
   -> a new shell is spawned inside screen
 - try cursor movement using <HOME> or <END>


Actual behavior
---------------
   -> nothing happens

Expected behavior
-----------------
   -> Cursor moves either to beginning or the end of the line


Workaround
----------
Adding these two lines to ~/.inputrc helps:

"\e[1~": beginning-of-line
"\e[4~": end-of-line


N.B.: The following does *not* help:
--- snip ---
user@box:~> export TERM=xterm-256color
--- snip ---
