I was asked explicitely about the difference of writing a Mercurial extension and of writing some addition for git in C, so I answered that.

Since that "script" will likely be an extension which will use the core function instead of the UI command, it won't break.

Stuff which does command line parsing can naturally break when I change the output. But it can also directly use the advanced features.

Means git can provide additional commands and only has the limitation that I can't overwrite the basic commands, right?

But we're slowly moving off topic, aside from "OK, git also has extensions - they are called external commands".
