    Problem Text
    This test may fail on implementations because of a possible side
    effect of test purpose 192.

    The test in question tests the following assertion:

    If the User Portability Utilities option is supported: When one of the
    mailx commands copy, file, save, set, source, or write has an unquoted
    file argument that does not begin with +, the file argument is subjected
    to the process of shell word expansions.

    To test this assertion, the test purpose makes use of a data file
    (DATA/194.1) that includes the lines

    set dot
    copy 1 mail*1

    The intent of the "copy" command is to copy message number 1 to a
    file named "mailx_out_1", which is created as an empty file by the
    test purpose. When we run this test by itself it passes on our system.
    However, when we run it in conjunction with the test for assertion 192
    then assertion 194 fails. The reason is that the test purpose for
    assertion 192 creates a file named "mailx_192_in_1" and does not
    remove it. (Instead, the test purpose attempts to remove a file named
    "mailx_192_in" there is no such file.) Thus when the copy command in
    the test for assertion 194 expands the string "mail*1" it gets expanded
    (in accordance with the requirements of the assertion) to two file names:

    copy 1 mailx_192_in_1 mailx_out_1

    The semantics of such a command are unspecified.

    When we change the cleanup code in the test for assertion 192 from

    rm -f a*a mailx_192_in
    to
    rm -f a*a mailx_192_in_1

    then assertion 194 passes on our system. This behavior is reliably
    repeatable. Clearly this is a test suite defect.
