Then it loads either xterm.el or screen.el (which loads xterm.el).
xterm.el has a function called xterm--init-bracketed-paste-mode, can
you see if it gets called at startup?

This is new with Emacs 25, so 24.5 shouldn't have it.

The stuff that gets put into the selection is up to the application
that owns the selection, right?
