        Indexing array variables doesn't work for ranges starting not at
        the first element. The manual says:
        ... If PARAMETER is an array name indexed by `@' or `*', the
        result is the LENGTH members of the array beginning with
        With an index of address@hidden, the result is nothing unless OFFSET is 
        last element.
        This has worked properly with bash 2, I believe.
        I assume I am wasting my time reporting this, but there isn't a
        searchable bug database mentioned on 

        showargs() {
        echo "argv (#=$#): ""$@"
        while [ $i -le $# ]; do
            echo "argv[$i]:" "'${!i}'"
            i=$(($i + 1))

        updates=( update update/deltas )
        showargs address@hidden
        showargs "address@hidden:1}"
        echo --
        updates=( update update/deltas word3 )
        showargs address@hidden
        showargs "address@hidden:1}"
        showargs "address@hidden:2}"
        This produces:
        argv (#=2): update update/deltas
        argv[0]: './mkcd/mkmd5'
        argv[1]: 'update'
        argv[2]: 'update/deltas'
        argv (#=0):
        argv[0]: './mkcd/mkmd5'
        argv (#=3): update update/deltas word3
        argv[0]: './mkcd/mkmd5'
        argv[1]: 'update'
        argv[2]: 'update/deltas'
        argv[3]: 'word3'
        argv (#=2): update/deltas word3
        argv[0]: './mkcd/mkmd5'
        argv[1]: 'update/deltas'
        argv[2]: 'word3'
        argv (#=0):
        argv[0]: './mkcd/mkmd5'
