[PATCH v3] git-gui: Handle Ctrl + BS/Del in the commit msg

From: Ismael Luceno <redacted>

- Control+BackSpace: Delete word to the left of the cursor.
- Control+Delete   : Delete word to the right of the cursor.

Originally introduced by BRIEF and Turbo Vision between 1985 and 1992,
they were adopted by most CUA-Compliant UIs, including those of: OS/2,
Windows, Mac OS, Qt, GTK, Open/Libre Office, Gecko, and GNU Emacs.

In both cases Tk already implements the functionality bound to other key
combination, so we use that.

Graphical examples:

Deleting to the left:
        v------ pointer
X_WORD____X
  ^-----^------ selection

Deleting to the right:
  v--------- pointer
X_WORD_X
  ^--^------ selection

I'm re-submitting the patch after >1 year.

Notes:
    Changes since v2:
    - Reimplemented via existing events, which correctly delete spaces.
    - Further improved commit message.
    
    Changes since v1:
    - Improved commit message.

Hi Ismael,

Don't use "Control" directly to maintain compatibility with MacOS. Use 
$M1B like the surrounding code does. I fixed it up locally, so no need 
to send in a new version. You can find the fixed up version here [1]. 
Test it if you'd like.

Will merge it in. Thanks.
