I'm thinking they mean the Bourne(-style) shell, where this syntax means that test is run, either commit or revert is run. That is, it is a shorthand for: if test then commit else revert fi Presumably the point is to encourage you to keep your code changes and tests so small that you are OK with losing work.

It's actually equivalent to if test; then commit || revert else revert fi Or in another language: try { test commit } catch { revert } This is because test && commit is evaluated, and the resulting value is the left side of expr || revert Not sure if that was intentional, but it's a very nice one liner assuming either your commit never fails, or your commit runs extra tests, and you want to revert if those fail.
