I thought that hierarchical state machine is a pretty standard programming pattern, but I've never seen the name "statechart" before. Is it the same thing, or are there any differences that I didn't notice?

It's not exactly the same. Statecharts have more "features" than just hierarchical states: - Parallel (orthogonal) states - History (shallow, deep) states - Entry, exit, transition actions - Delays - "Throughout" actions (activities) - Etc.
