Thankks! I upgraded my kernel to 6.19.10 and patched the system-wide
terminfo database. And it works liek a charm, so really, thankyou.

For those who would like to test the feature.

## Reproducing the "problem"

Run ls and then a command like mutt or lynx.

When you leave the second program, its output remains on the screen and
you cannot see your previous commands

## Verifying that the problem has been fixed

Do the same and after leaving the second program you will be able to
read the output of ls that you had run before running mutt or lynx.

Question: I am wondering how this should be integrated to distributions.
I guess it's not as simple as upgrading terminfo whne the kernel is
upgraded, because there always is the possibility to boot an older
kernel that does not support the feature.

Or is it okay if the corresponding escape sequences are sent even though
they are not supported? In which case the modification could simply be
upstreamed to terminfo,, independently of the installed kernel?

Seb.
