because we are going to delete the whole lines that contain match, but nobody
said that they contain only match. Both solutions does not work for patterns
with \zs and \ze, maybe it is better to do the following:

    function! s:MarkToDel(todelete, sline, submatch)
        let lnum=len(substitute(a:submatch, '\n\@!.', '', 'g'))
        call add(a:todelete, [a:sline, lnum])
        return a:submatch
    endfunction
    function! DeleteMatchingLines(pattern)
        let todelete=[]
        let savedgdefault=&gdefault
        set nogdefault
        try
            execute '%s/'.escape(a:pattern, '/').
                        \'/\=s:MarkToDel(todelete, line("."), submatch(0))'
        finally
            let &gdefault=savedgdefault
        endtry
        let deleted=0
        for [sline, lnum] in todelete
            let sline-=deleted
            let deleted+=lnum+1
            let range=sline.','.(sline+lnum)
            execute range.'delete _'
        endfor
    endfunction

How should I use your function? I've copied it to my .vimrc but don't know what to do next :-) 

Thank you again for your time (and Tim's too!)
