make edlin understand a few important control keys
Hi Fredrik,

Please find an updated version of the patch attached to this e-mail. I
hope that you still accept it via e-mail because the former patch was
sent the same way ;-).
I have extended the documentation to list the new key combinations and
added tests to make sure they work.
Kind regards,

Subject: [PATCH] [EDLIN] support a few more control keys
Add support for the following control keys that many users have become
accustomed to:
- <CTRL>+W : backward kill word
- <CTRL>+U : backward kill line
- <HOME> : goto start of line
- <END> : goto end of line
- <CTRL>+<LEFT> : backward word
- <CTRL>+<RIGHT> : forward word
It seems that the <CTRL>+<LEFT|RIGHT> control key sequences are
different between terminal emulators, therefore a few possible
combinations were added (similar to how libreadline is configured).
Documentation and tests are extended to reflect the new functionality.
