svn commit: r293002 - head/bin/sh

Log:
  sh: Remove redundant CTLQUOTEMARK checks.
  
  With the new expand.c code, the intermediate representation passed to the
  pathname generation code only contains CTLESC, not CTLQUOTEMARK.
  
  CTLQUOTEMARK now only occurs in the text of NARG nodes (output of the
  parser).
