indeed!  and...isn't pcvt gone?

   248  #if _MACHINE_ARCH == i386
   249          /* XXX.  Fix this, pcvt people! */
   250          static char ttyletters[] = "pqrstuwxyzPQRST";
   251  #else
   252          static char ttyletters[] = "pqrstuvwxyzPQRST";
   253  #endif

so...how does it work?  i don't see a way for it to exit the
while/switch without returning an error...maybe i'm reading it wrong?
