What do you mean by "many" terminal emulators? I'm sure that most
modern terminal emulators in the market simply send the End key input
with the sequence defined by the termcap entry `@7' or the terminfo
entry `kend'. I searched in the terminfo database for terminfo entry
`kll' (corresponding to termcap `kH'), but TERM=att4415-*,
TERM=att5420_2*, and TERM=mach* seem to distinguish End and the
LowerLeft (or HomeDown), though I'm not sure if they are physical TTYs
or emulators. Other terminals that provide distinct sequences for
terminfo `kll' (termcap `kH') are TERM= amiga-vnc, bsdos*,
{,new,mem,scr}hp*, mono-emx, {,old}pc3, pcvt*, vip*, but I'm not sure
if we should call them "many" terminal emulators. Also, I'm not sure
if they are still used terminals.

In addition, tmux, which covers as wide a range of terminfo entries as
possible because of its nature, doesn't seem to cover `kll' at all,
while it covers all possible variants of `kend', `kEND', `kEND{3..7}'
for modified End keys.

I feel that including unrelated changes in a single patch is typical
in an AI-generated one.
