script(1) is a utility to record a shell session into a file. If you just run
'script' with no arguments, script(1) will launch your default shell while
recording the input/output, as in the following transcript:

lj at panoramix ~ $ script
Script started, output log file is 'typescript'.
lj at panoramix ~ $ printf '\e[31mHello world\e[0m\n'
Hello world
lj at panoramix ~ $ exit
exit
Script done.
lj at panoramix ~ $

After exiting the inner shell spawned by script, the current working directory
will contain a file named by default 'typescript' which will contain _all_ the
input (including deleted characters and the backspaces that deleted them!) and
output to the session. If your system's 'cat' command supports the '-v' switch,
the real contents of the 'typescript' file can be viewed with it:

lj at panoramix ~ $ cat -v typescript

TTY="/dev/pts/1" COLUMNS="197" LINES="47"]

On Linux, script(1) is typically included in the util-linux package, which will
be typically be installed as part of the base system. script(1) comes from
3BSD, so it is widely available on Unix-like systems. A newer alternative would
be asciinema, which allows creating nice screencasts.

So, in summary, if you can run zypper inside a script(1) session reproducing
the offending reflow behavior, and send the resulting 'typescript' file, it
would allow us to determine what exactly is zypper sending to the terminal.
