vim-bracketed-paste enables transparent pasting into vim. (i.e. no more set paste!)

Installation

I recommend using pathogen. Once you have installed pathogen:

cd ~/.vim/bundle
git clone https://github.com/ConradIrwin/vim-bracketed-paste

Otherwise just copy-paste everything from plugin/bracketed-paste.vim into your ~/.vimrc.

Usage

You need to be using a modern xterm-compatible terminal emulator (xterm, urxvt, and iTerm2 are known to work, and modern gnome-terminal should too) that supports bracketed paste mode.

Then whenever you paste into your terminal emulator using command+v or shift+insert, vim will automatically :set paste for you.

The code for this plugin was taken from Chis Page's answer to a StackOverflow question, I just packaged it.
