+ * Copy no more than COUNT bytes of the null-terminated string from
+ * SRC to DST.  If SRC does not cover all of COUNT, the balance is
+ * zeroed.
+ *
+ * Or, rather, if the kernel cared about that weird ANSI quirk.  This
+ * version has cropped that bit o' nastiness as well as assuming that
+ * __stxncpy is in range of a branch.
