Plugin manager in vimrc

Simple plugin manager in vimrc (see first few lines of the snippet for description; sorry, at time of writing I can't do any formatting in this description)

" I call this snippet: Poor man's plugin downloader
"
" This snippet allows you to define your plugins in vimrc, like so (one plugin per line or many plugins per line):
" Pl 'tpope/vim-repeat'
" Pl 'tpope/vim-sensible'  'tpope/vim-commentary' 'tpope/vim-eunuch'
" 
" Next time you start vim, these plugins will be fetched from github and enabled.
" 
" Existing plugins can be updated with:
" :UpdatePlugins
" 
" Or, if you have vim-dispatch, plugins can be updated in the background with:
" :UpdatePlugins!
" 
" This snippet relies on battle-tested vim-pathogen to do the heavy lifting.
" --------------------------------------------------------------------------

" Modify the 'Plugins {{{' section below to specify your plugins
