* NEWS: Update description of string changes. Mention print/s.

	* c-valprint.c (textual_element_type): New.
	(c_val_print): Use it.  Do not skip address printing for pointers
	with a string format.
	(c_value_print): Doc update.
	* dwarf2read.c (read_array_type): Use make_vector_type.
	* gdbtypes.c (make_vector_type): New.
	(init_vector_type): Use it.
	(gdbtypes_post_init): Initialize builtin_true_unsigned_char.
	(_initialize_gdbtypes): Mark int8_t and uint8_t as TYPE_FLAG_NOTTEXT.
	* gdbtypes.h (struct builtin_type): Add builtin_true_unsigned_char.
	(TYPE_FLAG_NOTTEXT, TYPE_NOTTEXT): New.
	(make_vector_type): New.
	* printcmd.c (print_formatted): Only handle 's' and 'i' for examine.
	Call the language print routine for string format.
	(print_scalar_formatted): Call val_print for string format.  Handle
	unsigned original types for char format.
	(validate_format): Do not reject string format.
	* stabsread.c (read_type): Use make_vector_type.
	* xml-tdesc.c (tdesc_start_vector): Use init_vector_type.

	* gdb.texinfo (Output Formats): Update 'c' description.  Describe 's'.
	(Examining Memory): Update mentions of the 's' format.
	(Automatic Display): Likewise.

	* gdb.arch/i386-sse.exp: Do not expect character constants.
	* gdb.base/charsign.c, gdb.base/charsign.exp: Delete.
	* gdb.base/display.exp: Allow print/s.
	* gdb.base/printcmds.exp, gdb.base/setvar.exp: Revert signed
	and unsigned char array changes.
