Up until now the agnoster theme with enabled inline git branch display did not work properly for bare repos.
This was caused by `git rev-parse --show-toplevel` returning empty string for bare repos. In that case it now uses the git directory as root.
Your bare repo should be displayed properly (although you usually won't really navigate through a bare git repo, this is nice to have.
The agnoster theme now supports:
* Setting color for all kinds of elements, by setting an appropiate config variable to the color name in your zshrc
Example: AGNOSTER_GIT_DIRTY_BG=red # Set the git prompt background color to red for dirty repos
* Allowing to separate the git root and the relative path in your prompt by setting AGNOSTER_GIT_INLINE to 'true'
You will then have a segment for the git root (ie. ~/.oh-my-zsh) followed by the existing git branch segment (ie. master) and
finally the relative directory path (ie. themes)
* By setting AGNOSTER_STATUS_RETVAL_NUMERIC to 'true', The return value in the status prompt will become a number instead of a cross.
