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.
This removes the deprecation warning about absolute permalinks. Absolute Permalinks will be the default as of Jekyll v1.1: http://jekyllrb.com/docs/upgrading/
The license text is shown as preformatted text; therefore we
need to wrap it to a sane length (like 80 characters) to
keep it readable.
In addition, we must do any formatting or indentation in the
source file. Both BSD licenses contain a list of conditions
that should be indented like a list, with blank lines in
between.
We could also potentially number the clauses; FreeBSD does
in its copy, but the OSI versions do not.
Pointing to `/artistic` is a broken link, since the content
is in `licenses/`. Follow the lead of other licenses, which
use a relative link that works.
