	* ms-chart.c (xl_chart_import_error_bar): Avoid crash in missing
	parent-series case.  Fixes #514630.

	* ms-formula-read.c (excel_parse_formula1, excel_parse_formula):
	Grow a maxlen argument and make sure we do not read more.  Fixes
	#514637.

	* ms-excel-read.c (excel_read_string_header, excel_get_text): Grow
	an array_length argument and make sure we do not read more array
	data than call.  All callers changed.
	(excel_biff_text, excel_biff_text_1, excel_biff_text_2): New
	Biff-record based wrappers for excel_get_text.
	(excel_formula_shared): Make sure to copy the data behind the
	expression too.
