lisp/ChangeLog:

2007-10-10  John W. Eaton  <jwe@octave.org>

	* progmodes/octave-mod.el (octave-looking-at-kw,
	octave-re-search-forward-kw, octave-re-search-backward-kw):
	New functions.
	(octave-in-defun-p, calculate-octave-indent,
	octave-blink-matching-block-open, octave-beginning-of-defun,
	octave-auto-fill): Use octave-looking-at-kw instead of looking-at
	to search for regexps that contain case-sensitive keywords.
	(octave-beginning-of-defun): Use octave-re-search-backward-kw
	instead of re-search-backward to search for regexps that contain
	case-sensitive keywords.
	(octave-scan-blocks): Likewise, for octave-re-search-forward-kw.
