mvim updated to handle command line options and stdin

mvim

#!/bin/sh
#
# This shell script passes all its arguments to the binary inside the
# MacVim.app application bundle.  If you make links to this script as view,
# gvim, etc., then it will peek at the name used to call it and set options
# appropriately.
#
# Based on a script by Wout Mertens and suggestions from Laurent Bihanic.  This
# version is the fault of Benji Fisher, 16 May 2005 (with modifications by Nico
# Weber and Bjorn Winckler, Aug 13 2007).
# First, check "All the Usual Suspects" for the location of the Vim.app bundle.
# You can short-circuit this by setting the VIM_APP_DIR environment variable
# or by un-commenting and editing the following line:
# VIM_APP_DIR=/Applications

# Updated by shakefu to handle stdin, and -options
