[PATCH] t/t6000lib.sh: tr portability fix fix

[Brandon Casey <casey@nrlssc.navy.mil>]

Some versions of tr have a problem with character sets which begin with
multiple dashes and attempt to interpret them as long options. Escape
each dash to avoid this confusion and also prevent a possible
interpretation of the dashes as a range.

Here's the version with escaped dashes. If you do the sed version, it's
something to compare to for readability.
