AFAIK there aren't any propertized strings in purespace, because
`purecopy` doesn't copy the properties:
static Lisp_Object
purecopy (Lisp_Object obj)
{
if (FIXNUMP (obj)
|| (! SYMBOLP (obj) && PURE_P (XPNTR (obj)))
|| SUBRP (obj))
return obj; /* Already pure. */
if (STRINGP (obj) && XSTRING (obj)->u.s.intervals)
message_with_string ("Dropping text-properties while making string `%s' pure",
obj, true);
