Matthias Clasen cc777da9c1 Use g_vasprintf() and g_string_append_len(), thus enabling embedded nuls
2003-06-06  Matthias Clasen  <maclas@gmx.de>

	* glib/gstring.c (g_string_append_printf_internal): Use
	g_vasprintf() and g_string_append_len(), thus enabling embedded
	nuls in the result of g_string_printf().  (#92492, Owen Taylor)

	* tests/string-test.c: Add a test for embedded nuls in the
	result of g_string_printf().
