Broken control+<arrow> handling when TERM=xterm*

[larsks]

Out of the box, you can use ctrl+leftarrow and ctrl+rightarrow to jump backwards or forwards by word when editing the bash command line. When running bash under mtm when TERM outside of mtm is set to either xterm or xterm-256color, this is no longer case -- these key combinations generate garbage on the cli rather than moving the cursor.

This is the result of typing ctrl+leftarrow twice, followed by ctrl+rightarrow twice, with the cursor positioned at the end of the command line:

$ echo this is a testȪȪȹȹ

If I set TERM to a non-xterm variant, e.g:

TERM=screen mtm

Or:

TERM=vt100 mtm

Then ctrl+<arrow> works as expected
