Avoid non-standard escape sequences in tr command
POSIX says
The <backslash>-escape sequences in Escape Sequences and
Associated Actions ( '\\', '\a', '\b', '\f', '\n', '\r', '\t',
'\v' ) shall be supported. The results of using any other
character, other than an octal digit, following the <backslash>
are unspecified. Also, if there is no character following the
<backslash>, the results are unspecified.
Instead, just use `--` to separate options and operands, since tr(1)
is required to conform to the Utility Syntax Guidelines.
