Re: Git hooks

Hey Shawn,

Thanks for that. I agree with Erik about the "Unfortunately,". I also wonder if 
the setup-hooks.sh could use a little `git rev-parse` something something to look for the 
repo's .git. Like this:

```
gitdir="$(git rev-parse --git-dir)"
[[ $? -eq 0 ]] || {
  printf "%s: No .git directory found.\n" "$0"
  exit 1
}
ln -fs \
  "$(git rev-parse --show-toplevel)/hooks/pre-commit.sh" \
  "${gitdir}/hooks/pre-commit || \
...
```

Hopefully that will be more flexible/robust than assuming we're already in the 
repo's root directory.
