    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.
