I think `git branch` here wasn't intended to be taken literally. If anything, you'd use a plumbing command to get the branch, not a porcelain command. I think they just meant that some commands that might be run might in turn run programs specified in the config file (either now or in the future).

  `git status`. This essentially has a "prompt" mode with `--porcelain`, which can even print branch and stash state, so it features all of the information for a prompt. Prompts have been mentioned in adding the v2 porcelain format[0] It will call the fsmonitor hook configured in core.fsmonitor - this is supposed to speed up figuring out which files to check. The official git-prompt.sh calls `git diff`, which will do the same[1].
