add space deletion to previous tabstop behavior

[Carreau]

this allows to bind backspace to delete space until previous tabstop.
is deleting cm.tabSize space is not possible, it falls back to deleting
1 character, or delete selection if smth is selected.

hi,

I was not able to achieve the behavior I wanted only by configuring codemirror with availlable options, so I patched it and propose the change upstream.
Basically I want to indent with (4) space, and delete to the previous n*tabSize when possible, otherwise fall back to del 1 character.

Thanks.

Hi Matthias,

This does not have to be integrated in CodeMirror itself. If you just, in your code, do

CodeMirror.commands.delSpaceToPrevTabStop = function(cm) { /* your code here */ };

you can add a command. Or, even simpler, just associate the key with that function directly, without going through a command.

As I don't want to bloat up core CodeMirror with lots of useful but niche commands, I am not merging this.

Best,
Marijn

ok, no problem, I was just a proposal, I'm fine with defying this externally.
Great workBTW :-)
