We’ve had a bug raised in Debian (#707308) reporting that Screen’s
terminfo does not advertise the erase_chars (ECH) capability.
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=707308
The documentation states that ESC [ X is recognized, and the code supports
this; it is just missing from terminfo/screeninfo.src.
This causes terminfo-driven tools/apps to assume ECH is unavailable (for
example, tput ech under TERM=screen).
Minimal fix is to add:
ech=\E[%p1%dX,
to the screen, screen-bce, and screen-s entries.
Patch attached.
