	* src/sheet.c (sheet_cell_insert) : make it clear that this routine
	  does not link the expression or register the dependencies.
	(sheet_cell_remove_from_hash) : document state changes and use
	  dependend_unlink.
	(cb_remove_allcells) : cell_destroy will unlink.
	(cb_collect_cell) : be clear that the results are unlinked.
	(colrow_move) : some docs.
	(sheet_move_range) : simplify now that the collected cells are
	  unlinked rather than just having their depends dropped.

	* src/eval.c (cell_add_dependencies) : delete.
	(cell_drop_dependencies) : delete.

	* src/style.c (style_font_new_simple) : If we can't find a font check
	  a map to see if we know of something similar.
	(get_substitute_font) : moved here from the XL importer.
