RE: Killing punctuation chars enclosed with delimiters via backward-kill-word

[Doug Lewan]

Dmitry,

M-d invokes delete-word. The deletion is based on word-syntax.

You could write an different command using `skip-syntax-forward' and map the 
new command to M-d.

`backward-kill-word' will have the same issue.

(FYI M-h runs mark-paragraph for me. I'm using emacs 24.3.)

Subject: Killing punctuation chars enclosed with delimiters via 
backward-kill-word

Hi list. Here is my question.

Suppose this text:

int variable;
[
 ^
 |
 +- Pressing M-h here will erase ``variable;''. I don't like this behavior.

Is there a functionality to kill only punctuation char if it is enclosed by
delimiters or newlines?

More examples:

int array [
          ^
          |
          + - Pressing M-h here kills ``array'' as well

int array []
            ^
            |
            + - Pressing M-h here kills ``array'' as well


         + - pressing M-d Here kills ``int''
         |
         V
int array [];
int val;


Any ideas?

Could this be resolved by hacking syntax-table? Or we should rewrite
``backward-kill-ford'' and ``kill-word'' functions?
