Yes.  GNU tr and similar programs accept options anywhere on the
command line.  This is different from POSIX and is therefore affected
by the setting of POSIXLY_CORRECT in the environment.  Here are two
suggested workarounds.

  echo xyzt | tr -- 'xyzt' '----'

  echo xyzt | POSIXLY_CORRECT=1 tr 'xyzt' '----'
