You can probably get auto-fill-mode to do something like what you want.
You'll probably need something like:
(defun my-tcl-comment-line-break-function (&optional soft)
(if (tcl-in-string-p) (insert "\\"))
(comment-indent-new-line soft))
(defun my-tcl-mode-hook ()
...your other Tcl-mode customizations here...
(set (make-local-variable 'comment-line-break-function)
'my-tcl-comment-line-break-function))
(add-hook 'tcl-mode-hook 'my-tcl-mode-hook)
But tcl-mode does not define tcl-in-string-p. If you use Emacs-CVS (and
font-lock), you can try to use
(defun tcl-in-string-p () (nth 3 (syntax-ppss)))
if not, you can try
(defun tcl-in-string-p ()
(nth 3 (parse-partial-sexp (point-min) (point))))
but that may end up being too slow if you're editing a large Tcl buffer
(syntax-ppss is much faster because it uses caching).
Another option is something like
(defun tcl-in-string-p ()
(save-excursion
(let ((pos (point)))
(beginning-of-defun)
(nth 3 (parse-partial-sexp (point) pos)))))
which should stay reasonably fast.
Stefan
