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.
