Fixed a FIXME comment.

2000-05-16  Christopher James Lahey  <clahey@helixcode.com>

	* e-table-sorted-variable.c: Fixed a FIXME comment.

	* e-table-header.c, e-table-header.h: Added code to put off size
	calculation to the idle loop.  Added code to not resize columns
	with 0 expansion.  Removed the set_width function; it's been
	replaced with a Gtk+ arg.

	* Makefile.am: Added e-table-defines.h to the Makefile.am.

	* e-table-defines.h: A new file containing some #defines for use
	in ETable.
