    Problem Summary TSD4C.00115 The test may fail on implementations that default the ERASE character to the # character.
    Problem Text
    The test may fail on implementations that default the ERASE character
    to the # character.

    Test 709 expects that the "$#" token will cause the shell to return
    the number of paramaters passed to the command under test.

    The test sends the "$#" token through a psuedo terminal to the command
    under test. The test fails because the "#" character is treated as an
    ERASE character by the psuedo terminal, which causes the preceeding
    character to be erased.

    During test setup, the test creates a child process which opens the
    psuedo terminal. When a psuedo terminal is opened for the first time,
    the "#" character defaults to the canonical ERASE character on our
    implementation.

    Since spawning a subshell does not cause the .profile file to be
    executed, the "#" is not set to something reasonable, such as '^H'.

    The standard does not require the ERASE character to be '^H' and does
    not require that spawned shells execute the .profile file. The test
    should be corrected to avoid this assumption.
