Github commit, diff does not show changes

You can check the diff from your local machine if GitHub cannot show it to you

 $ git show the-commit-id path/to/the/file

Github doesn't show large diffs probably because it is quite js-intensive and will likely freeze your browser. Solution would be to not rely on github for browsing diffs which you can see in any git-gui you have

e.g. tig is pretty handy.

$ tig commithash
