I'm not actually sure the purpose of this, but I can't find any other linux-based terminal that currently does this.

Given this diff:

It appears that xterm is explicitly sending a CTRL+h keypress when you press shift+backspace. This causes issues if you want to use CTRL+h for different reasons, such as using it as a mapping to swap tmux panes. It causes the most issues when you're typing things like environment variables and make a mistake so you hit backspace (often without releasing shift) and then tmux (or whatever extra actions you have ctrl+h bound to) gets fired.

It looks like it was added in the very first commit here: Tyriar@8bc844c

Is there any way I can disable this behaviour or can anyone explain the purpose?
