set rtp+=.... command length limitation: incorrect plugin paths initialization

[hoopoepg]

hi

something about me: windows8x64, vim7.4, 32bit

i found strange issue in vundle processing: one of the path in rtp is truncated after vim loaded. after investigation i found that vim command 'set rtp+=...' has limitation by length & in case if somebody uses a lot of plugins loaded by vundle - vundle may initialize path to plugins incorrectly.

fix: use loop to add paths to rtp instead of adding paths as single command

vimfiles\bundle\Vundle.vim\autoload\vundle\config.vim: 195

func! s:rtp_add_a()
  let paths = map(copy(g:bundles), 'v:val.rtpath')
  for item in paths
    exec 'set rtp^='.fnameescape(item)
  endfor
  for item in paths
    exec 'set rtp+='.fnameescape(item.'/after')
  endfor
endf

thank you
