Script for checking git status of many git repositories

Added color and empty args behavior

I can't seem to get this to work with more than one directory. I've tried various syntax combos ..

ARGS=('folder1' 'folder2')

and also

ARGS[0]='folder1'
ARGS[1]='folder2'

But I can't seem to get it to search past the first folder. I'm not that experienced with bash scripting - how do I make this for statement loop through the array?

Figured it out .. see https://gist.github.com/3666392
