Related git+fzf:

    [alias]
      fza = "!git ls-files -m -o --exclude-standard | fzf -m --print0 | xargs -0 git add"

Then if you run "git fza" you'll get a list of changed files in your repo, which you can use TAB to select/deselect. Hit enter and the selected files will be staged, ready for a commit. Extra cool is that it works from any subdirectory of your repo because it always lists files from the root of the repository. It's really useful for selectively adding lots of files from the command line.

I then alias "ga" to "git fza" for even less typing :)

Excuse my ignorance, but what does this command do?
