    Problem Text
    This test may generate misleading output.

    This test reads a number of lines from a file then sends
    them to a function for output to the test journal. On our system
    one of the lines read has the following general format

    YY_DECL char * yytext = yy_tbuf;

    The test assigns this line to a varaible called line. It then
    tries to send this to the journal via the command.

    JrnlMsg $line

    The shell does variable substitution which expands the command to

    JrnlMsg YY_DECL char * yytext = yy_tbuf;

    It then tries pathname expansion. Since the * matches everything
    in the current directory we get the unexpected output shown above.

    Since this contains information necessary to inspect and approve the
    output we feel a TSD should be granted.

    This problem also manifests itself with other less critical lines that
    also contain the string "yytext" (mostly comments containing "*" or
    beginning with "/*" which expands to all files in the root directory).

    If the JrnlMsg line is changed to

    JrnlMsg "$line"

    this behavior should not occur.

    The same problem applies to test 52.
