Remove git integration
Wrap statusline function invocation in augroup
Add installation instructions
My custom vim statusline (https://www.paritybit.ca/making-my-own-vim-statusline).
You can install this plugin using your favourite vim/neovim plugin manager.
Since I use Pathogen, here are explicit instructions for that plugin manager:
cd ~/.vim/bundle
git clone https://git.sr.ht/~jbauer/vim-fastline
