  SVN rev 219623 on 2011-03-13 20:02:39Z by jilles
  
  sh: Fix some parameter expansion variants ${#...}.
  
  These already worked: $# ${#} ${##} ${#-} ${#?}
  These now work as well: ${#+word} ${#-word} ${##word} ${#%word}
  
  There is an ambiguity in the standard with ${#?}: it could be the length of
  $? or it could be $# giving an error in the (impossible) case that it is not
  set. We continue to use the former interpretation as it seems more useful.
