	* ms-formula-read.c (excel_parse_formula) : Ok. take a 2nd crack at
	  the externsheet handling in area3d and ref3d for biff7.  It seems
	  like XL2k generates different idicies when exporting as XL95 than
	  XL95 did.  So have a fall back.  If the theory that
	    a+1 == -ixals, a, b are 0 based
	  fails.  Go back to
	    a   == ixals, and a, b are 1 based

	* ms-formula-read.c (ms_excel_parse_formula) : improve readability of
	  debug spew and send thing to stderr.
	Fix handling of extern names and refrences.  This time I think we've
	finally got it.

	* ms-excel-read.c : tidy up naming conventions
	    excel_read_<BIFFTAG>
	  - Use fprintf to keep g_warning and printfs in sync
	  - Use esheet for ExcelSheets and ewb for ExcelWorkbooks
	  - Use Sheet and wb for the gnumeric variants
	(ms_excel_sheet_new) : check to see if the sheet already exists
	  in case it was implicitly created in a SUPBOOK or EXTERNSHEET.
	  This will be useful when we start restoring external links shortly.
	(ms_excel_workbook_attach) : delete.
	(ms_excel_workbook_detach) : delete.
	(ms_excel_sheet_destroy) : clear out the sheet local extensheet
	  records for biff5.
	(excel_read_BOUNDSHEET) : use ms_excel_sheet_new.
	(excel_externsheet_v8) : rewrite to handle self ref.  Only partially
	  done.
	(supbook_get_sheet) : ditto.
	(excel_read_EXTERNSHEET_v8) : ditto.
	(excel_externsheet_v7) : fix to use local externsheets.
	(excel_read_EXTERNSHEET_v7) : rewrite and prep for external
	  references.
	(excel_workbook_get_name) : work around 'self ref' records for biff8.
	(excel_parse_name) : work on scoping.  works for biff7 not biff8.
	(ms_excel_handle_delayed_NAMEs) : delete.  the externsheet records are
	  enough.
	(excel_read_EXTERNNAME) : builtin names are just short forms for
	  names, they have special meanings to XL but no special behavior.
	(excel_read_NAME) : ditto.  Use the new externsheet setup and drop all
	  of the delayed parsing goo.
	(excel_read_XCT) : new.  prep for external references.
	(excel_read_CALCMODE) : new.  now that we support manual recalc.

	* ms-excel-read.c (ms_excel_parse_NAME) : It looks like some
	  builtinnames are just names, no definitions. eg 'Database'
	  It also looks like these sheet_indexes apply to externsheet records
	  for <= biff7 (see pivot.xls) rather than boundsheets.

	* src/workbook.c (workbook_foreach_cell_in_range) : fix.

	* src/position.c (rangeref_normalize) : fix.

	* src/validation.c (validation_eval) : don't unref the val expr too
	  early.

2002-10-21  Jody Goldberg <jody@gnome.org>

	* src/gui-file.c (gui_file_read) : handle workbooks with no sheets.
	* src/workbook-control-gui.c (wbcg_focus_cur_scg) : ditto.
	(show_gui) : ditto.

2002-10-21  Jody Goldberg <jody@gnome.org>

	* src/rendered-value.h : don't use short for width.

	* src/workbook.c (workbook_set_placeholder) : new.
	(workbook_is_placeholder) : ditto.

	* src/gui-util.c (cb_parent_mapped) : new utility.
	(gnumeric_set_transient) : handle the case where we are a transient
	  child of an unmapped parent.

	* src/expr.c (gnm_expr_equal) : name comparison should take scoping
	  into account too.
	(do_expr_as_string) : and here.
	(ets_hash) : use the name itself as a hash key.

	* src/expr-name.c (expr_name_add) : return a copy of the error
	  message.  And ensure that all NULL returns generate errors.
	(expr_name_new) : make this static and internal.
	(name_print_area) : delete.

	* src/dependent.c (workbook_unlink_3d_dep) : during destruction the
	  order hash may be gone.  This happens with names that contain 3d
	  references.

2002-10-17  Jody Goldberg <jody@gnome.org>

	* src/plugin-service.c (gnum_plugin_file_opener_open) : store the save
	  info before we load so that the file name is valid.
