Adding xterm-extras to Emacs

[Leo]

Dear all,

When I run emacs in terminal like xterm I find that xterm-extras.el¹
crucial. It makes almost all key bindings available in X also available
in terminal.

I wonder if we can include the file or add such functionality to
an appropriate existing package in Emacs.
