misc/tmux (and the tmux in base) both force the VERASE character to be DELETE, instead of leaving it alone at the user's preference. It even forcefully changes backspace into DELETE, breaking all my terminal settings. For decades I have set backspace ^H as the erase character, and forced my keyboards to produce the backspace character from the key which is clearly marked backspace. Tmux seems to think it knows my preferences better than me and forces its own ideas upon me. My systems are consistent and tmux messes it up. So I have local patches to fix it: it leaves the VERASE setting alone, so it stays the way you like it. It also doesn't translate keys into DEL any more. If you like DEL as your erase character, there is of course no change from the patch, as you will have set your terminals accordingly already. I want to add these patches to pkgsrc. I would also like to patch the base system tmux in the same way.
