  SVN rev 214524 on 2010-10-29 19:34:57Z by jilles
  
  sh: Fix some issues with CTL* bytes and ${var#pat}.
  
  subevalvar() incorrectly assumed that CTLESC bytes were present iff the
  expansion was quoted. However, they are present iff various processing such
  as word splitting is to be done later on.
  
  Example:
    v=@$e@$e@$e@
    y="${v##*"$e"}"
    echo "$y"
  failed if $e contained the magic CTLESC byte.
  
  Exp-run done by:        pav (with some other sh(1) changes)
