xterm and command line word movement: CTRL+RightArrow, CTRL+LeftArrow

[Zenaan Harkness <zen@freedbms.net>]

I'm running on sid.

With the following in ~/.inputrc :

$include /etc/inputrc
"\e[1;5C": forward-word
"\e[1;5D": backward-word
"\e[5C": forward-word
"\e[5D": backward-word
"\e\e[C": forward-word
"\e\e[D": backward-word

And running bind ~/.inputrc, CTRL+LeftArrow and
CTRL+RightArrow display the usual problematic ";5D"
and ";5C" character sequences.

Inside a GNU Screen session, the word jumping works as
expected. I would like it to work, even if I don't run screen.

How might I diagnose or fix this?

TIA
