Strictly speaking you right.  Though, this is nonsense IMHO.

  false && false
  false && true
  true  && false

does NOT exit with NetBSD's /bin/ksh, pdksh, mksh,
bash and heirloom sh. Linux's dash works differently
  'false && false' - does NOT exit
  'false && true'  - does NOT exit
  'true && false'  - exits

At the same time

  false || false

DOES exit in all these shells (including NetBSD /bin/sh).

Is there other online specification of the shell?
