muse-publish: Support orgtbl-mode style tables

2007-05-30  Michael Olson  <mwolson@gnu.org>

	* NEWS: Update.

	* lisp/muse-latex.el (muse-latex-markup-table): Deal with
	horizontal separators in tables.

	* lisp/muse-publish.el (muse-publish-markup-regexps): Recognize
	horizontal separators in tables.
	(muse-publish-trim-table): New function to remove initial and
	final blank columns from a table.
	(muse-publish-table-fields): Call `muse-publish-trim-table'.  Deal
	with horizontal separators, aka "hlines".

	* lisp/muse-regexps.el (muse-table-hline-regexp): New regexp that
	defines the syntax of a horizontal separator in a table.

	* lisp/muse-texinfo.el (muse-texinfo-markup-table): Deal with
	horizontal separators.  Publish header lines correctly.

	* lisp/muse-xml-common.el (muse-xml-sort-table): Deal with case
	where we have nonnumbers as a row type.  This ignores sorting for
	hlines.
	(muse-xml-markup-table): Deal with horizontal separators.  If the
	markup supports table groups, make hlines separate table groups.
	Otherwise, ignore them, since they cannot be marked up.  Together,
	these changes allow us to support orgtbl-mode tables.  Thanks to
	Carsten Dominik for the suggestion.
