Stop using exported variables

[supertopher]

We should pass the path as argument instead of exporting PEAR_WORKING_DIR. I think we can simply add it as another argument to uninstall and cycle... which i believe are the only two programs who need to know that location outside of the actual pair app

I also think we call git_dir=$(git rev-parse --git-dir) too many times. Either export that sucker or pass it in?

[salarkhan]

Btw I agree on passing PEAR_WORKING_DIR into cycle && uninstall

[supertopher]

i don't like calling things 20 times, but i like that it keeps the individual pieces capable of performing their job without being coupled

create-hook-file for example is fully capable of being a standalone program as it stands

Good point.
