horizontal scroll bars

[Elias P. <el...@us...>]

If I use this, as was suggested here:

"
function! Cream_wrap_init()
" initialize wrap (for statusline)

    " don't change state in special buffers
    " opsplorer
    if bufname("%") == "_opsplorer"
        return
    endif
    " calendar
    if bufname("%") == "__Calendar"
        return
    endif
    " tag list
    if bufname("%") == "__Tag_List__"
        return
    endif

    " used before
    if exists("g:CREAM_WRAP")
        if g:CREAM_WRAP == 1
            set wrap
            "set guioptions-=b
        else
            set nowrap
            execute "set lines=" . &lines - 2
            set guioptions+=b
        endif
    else
        " initialize on
        set wrap
        set guioptions-=b
        let g:CREAM_WRAP = 1
    endif

endfunction

function! Cream_wrap(mode)
" toggle word wrap

    " should already be initialized, but check anyway
    if exists("g:CREAM_WRAP")
        if g:CREAM_WRAP == 1
            let g:CREAM_WRAP = 0
            set nowrap
            "execute "set lines=" . &lines - 2
            set guioptions+=b
        else
            let g:CREAM_WRAP = 1
            set wrap
            set guioptions-=b
        endif
    else
        " error
        call Cream_error_warning(
            \ "g:CREAM_WRAP not initialized in Cream_wrap()")
    endif

    if a:mode == "v"
        normal gv
    endif

endfunction
"

I get horizontal scrollbars, but often get an error "E16: Invalid range:
-2" when switching windows. Is there a solution to this?
