## Override the default `git_prompt_info` function
## We decide if we show nothing, status with no branch (like in submodules) or
## with a branch using regex comparisons.
## Is there a better way than relying on error output?

## Override the default `git_prompt_status` function
## Preferably only use with multiline prompts
## Try to print a each change instead of just indicating if each type exists.
## This gives a better visual sense of how much has changed
## Status is computed from the short version of git status that lists out
##     xy filename1
##     xy filename2
## where x and y are statuses such as A (added), M (modified). Details in the
## git-status manpage.
## TODO Is this as fast as it gets? Maybe. The speed of this script appears to
## be limited by the speed of --porcelain or -s in any given repo.

## Override the default `current_repository` function
## Cope with non-ssh repos by not relying on ':'. Instead, we look for text
## between a '/' and '.git'.

## We don't need to test if HEAD is a symbolic ref - that gets controlled in
## git_prompt_info(). Unlike `current_branch` there are no oh-my-zsh shortcuts
## that will be broken if we don't test for this.
