Fix bug #6250: Numbers in definition lists incorrectly recognized

2007-06-15  Michael Olson  <mwolson@gnu.org>

	* lisp/muse-regexps.el (muse-list-item-regexp): Put definition
	list regexp part before other parts.
	(muse-ol-item-regexp): New regexp that specifies how to match an
	ordered list item.
	(muse-ul-item-regexp): New regexp that specifies how to match an
	unordered list item.
	(muse-table-field-regexp): New regexp that specifies how to match
	a definition list entry.

	* lisp/muse.el: Wrap muse-line-beginning-position and
	muse-line-end-position in `eval-and-compile', since they are now
	used in muse.el.
	(muse-list-item-type): Use a simpler algorithm for detecting which
	kind of list item we have.  This fixes a bug where a number in a
	definition list term was being detected incorrectly as an ordered
	list item.  Fixes bug #6250.
	(muse-forward-list-item): Get the entire line with the list item.
	For some reason, Emacs 21 was not populating match 2 correctly,
	unlike Emacs 22, so this workaround was needed.
