    Problem Text
    The test may fail on all implementations because of a typo.

    For tp333(), the assertion says:

    # When the command write \e! file is called, then ex considers the !
    # character to be part of the file name to be read and does not invoke
    # the command interpreter.

    This is saying that if I type "write \!file" in ex, the '!' will be taken
    literally since it is escaped.

    From tp333():

    excmd="write \!ex_out_1\nq!\n"
    printf "$excmd" | ex ex_data_1 > $CT_STDOUT 2> $CT_STDERR

    The commands

    excmd="write \!ex_out_1\nq!\n"
    printf "$excmd"

    will produce the following output:

    write !ex_out_1
    q!

    Notice that the '!' is not escaped, so it won't be taken literally by ex.
    Since $excmd is passed to printf as the format argument, it will be
    expanded by printf, so "\!" becomes "!" and ex will see "write !ex_out_1"
    not "write \!ex_out_1" as described in the documentation.

    The line:

    excmd="write \!ex_out_1\nq!\n"

    should be:

    excmd="write \\!ex_out_1\nq!\n"
