From https://github.com/github-linguist/linguist:

This library is used on GitHub.com to detect blob languages, ignore binary or vendored files, suppress generated files in diffs, and generate language breakdown graphs.

I assume that's what we see under Languages: Go 96.3% Shell 2.7% Other 1.0%

+1 for classifying the right blobs.
