* valprint.c (val_print_string): If errcode is set, always print

	an error, regardless of force_ellipsis.  In the non-EIO case,
	just print the error message rather than calling error().  Don't
	access *(bufptr-1) if bufptr points to the start of the buffer.
	When looking for '\0', don't increment bufptr and addr if bufptr
	started out already at limit.  If an error happens on fetching the
	first character, don't print the string.
