I routinely use the xterm "log to file" feature to capture terminal output.
When I do this with or without screen 4.9.1, lines are terminated with
carriage return, e.g:

    ice 1423 % cat -v Xterm-4.9.1.log
    ^M^M
    fun 80 % ^M^M
    fun 80 % ^M^M
    fun 80 % date^M^M
    Sun Sep  1 09:10:51 PDT 2024^M
    fun 81 % date^M^M
    Sun Sep  1 09:10:52 PDT 2024^M

But when I do the same with 5.0.0, I see escape sequences instead of carriage
returns:

    ice 1424 % cat -v Xterm-5.0.0.log
    ^[[34;1H
    ^[[1mice 4 % ^[[m^[[34;1H
    ^[[1mice 4 % ^[[m^[[34;1H
    ^[[1mice 4 % ^[[m^[[34;1H
    ^[[1mice 4 % ^[[mdate^[[34;1H
    Sun Sep  1 09:09:58 PDT 2024^[[34;1H
    ^[[1mice 5 % ^[[mdate^[[34;1H
    Sun Sep  1 09:09:59 PDT 2024^[[34;1H
    ^[[1mice 6 % ^[[mice 1425 %

I don't have an example but I've also see 5.0.0 use escape sequences instead
of the "space" character when capturing hex dumps like this:

    109.179 AA EB 89 B9 B2 01 02 44 6F 77 6E F3

Is there a way to go back to the 4.X behavior?
