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. 2011-03-13 20:02:39 +00:00			`# $FreeBSD$`
