Very nice, thanks! I tried it and I liked it very much.

I noted a few nits that might help improve it a bit.

Nit: maybe add "$ cd git" after that.

Nit: when building a "git-psuh" binary is created at the root of the
repo which will pollute the `git status` output. The usual way we deal
with that is by adding "/git-psuh" to the ".gitignore" at the root of
the repo.

Nit: maybe it could be a bit more clear that the previous printf()
call should be kept as is, otherwise the test added later will fail.

Nit: a ";" is missing at the end of the above line.

Nit: maybe add "builtin/psuh.c" at the end of the above line, so that
a `git add builtin/psuh.c` is not needed.

Nit: it seems that the above newline could be removed.

Thanks,
