Here's an email that I received from the maintainer of tmux about this
issue, indicating that it should be safe to remove the patch nowadays:
the reason they did that is because at least some freebsd versions have =
=20
xterm etc generate ^H by default and have ^H as verase in termios (stty) =
=20
=
=20
tmux always sends ^? as backspace to programs inside, but earlier =
=20
versions did not change the termios inside to set verase to ^? =
=20
=
=20
new versions do, so outside can have verase=3D^H, tmux will detect that is =
=20
backspace (from termios) and translate it to ^? inside as well as =
=20
setting verase to ^? in new windows so applications inside tmux use the =
=20
right thing =
=20
=
=20
this is all because terminfo kbs is too unreliable and so many =
=20
applications just blindly accept ^? anyway =
=20
=
=20
since your terminal on freebsd sends ^? (and termios is ^? too) either =
=20
you're using a terminal which uses that by default, you changed the =
=20
xterm deleteIsDEL property (like everyone else does), or freebsd changed =
=20
their default=20
