Subject: [PATCH] Make <ctrl>+<left arrow> and <ctrl>+<right arrow> work

On many systems <ctrl>+<left arrow> and <ctrl>+<right arrow> are mapped
to make the cursor move a word back and forward respectively. This is
done by mapping the `\e[1;5C` and `\e[1;5D` sequences.

This patch maps those sequences in this readline implementation as well.
