From: Johannes Schindelin <redacted>
The .NET version of Scalar has a `version` command. This was necessary
because it was versioned independently of Git.
Since Scalar is now tightly coupled with Git, it does not make sense for
them to show different versions. Therefore, it shows the same output as
`git version`. For backwards-compatibility with the .NET version,
`scalar version` prints to `stderr`, though (`git version` prints to
`stdout` instead).
