  14 # some of the tests:
  15 #
  16 # shell functions (do we care?)
  17 # var=${var:-val}
  18 # unset
  19 # set --
  20 # IFS parsing
  21 ## not exiting with -e and failed "if", the way Ultrix does (Ultrix 4.2?)
  22 # "$@" expands to zero arguments if passed zero arguments
  23 # $SHELL -c 'echo $1' bad good
  24 # test -x
  25 # positional parameters greater than 9
  26 # arithmetic expansion $(( ... ))
  27 # getopts
  28
  29 # For some tests we must run a sub-shell; $TESTSHELL says what to use.
  30 # If set, TESTSHELL must be an absolute pathname.
  31 # For example, on HP-UX 9, /bin/posix/sh is the supposedly-compliant shell.
