Since the license text is wrapped in `<pre>` with `white-space: pre-wrap` empty lines make the #license-text bigger than it actually is.
So, get rid of the empty newline at the end of the license text files since jekyll adds trailing spaces when it parses those.
"There are multiple variants of the
GPL each with different requirements"
Without a comma, this passage has no break where it would
be used to add the hint of nuance between GPL versions.
This removes the deprecation warning about absolute permalinks. Absolute Permalinks will be the default as of Jekyll v1.1: http://jekyllrb.com/docs/upgrading/
