I'm fine with [pre-commit-hooks] instead of [pre_commit hooks].

It's true that

  [pre-commit-hooks]
  foo = foo.sh
  [post-commit-hooks]
  bar = bar.sh

is slightly more complex that the Hg approach. But I prefer it because
its good practice to label hooks anyway and it scales nicer for multiple
hooks.
