powerbash is most consistent when it is the last profile.d script to run.

powerbash's Issues

Divergent history seems to confuse the git count

This command returns "2", but the git count indicator doesn't reflect that:

I have a hunch that it's getting confused by the divergent history (1 ahead, 2 behind):

Error in .git subfolder

Whenever I enter the .git folder of a local git repository, or run any command therein, I receive the error: fatal: this operation must be run in a work tree unless the git option is turned off.

Running Arch Linux.

Documentation should show requirements

There should be a notice somewhere that specifies that bash >= 4 is required. I'm on macos and it took me a while to figure out that this contains bash 4 features.
