Oscap source

Hey Shawn! OpenSCAP uses these en-dash (--) signs to separate date ranges pretty consistently. I would consider it bug, If you found a date range in OpenSCAP that uses hyphen. The very same date rages you can see in other projects (i.e. Spacewalk) too. The reason behind is the advice from Donald Knuth, the TeX hero ( http://web.mit.edu/jgross/www/LaTeX/texbook.pdf ).
