Here's a modified version that handles counts correctly:

function! ParagraphMove(delta, visual, count)
    normal m'
    normal |
    if a:visual
        normal gv
    endif

    if a:count == 0
        let limit = 1
    else
        let limit = a:count
    endif

    let i = 0
    while i < limit
        if a:delta > 0
            " first whitespace-only line following a non-whitespace character           
            let pos1 = search("\\S", "W")
            let pos2 = search("^\\s*$", "W")
            if pos1 == 0 || pos2 == 0
                let pos = search("\\%$", "W")
            endif
        elseif a:delta < 0
            " first whitespace-only line preceding a non-whitespace character           
            let pos1 = search("\\S", "bW")
            let pos2 = search("^\\s*$", "bW")
            if pos1 == 0 || pos2 == 0
                let pos = search("\\%^", "bW")
            endif
        endif
        let i += 1
    endwhile
    normal |
