app_completions.sh

#!/bin/sh
# This function performs app completion (open -a) based on known applications
# Originally by Kim Holburn http://www.holburn.net/
# Modified by Brett Terpstra because it wasn't working on 10.6.
# Added case insensitivity and LC_ALL='C' because unicode chars were breaking it.
# Then I went and modified the completion command
# even though I have little idea what I'm doing.
#
# also add 'o' to complete because I alias o to "open -a"
