[NTG-context] two bugs with compressed linenotes

Dear Hans, I have found two bugs with compressed linenotes that I reported (http://www.ntg.nl/pipermail/ntg-context/2013/073940.html and http://www.ntg.nl/pipermail/ntg-context/2013/073953.html). I would like to introduce ConTeXt for critical editions to some Spanish-speaking people and I think this is a very useful feature. Many thanks for your help, Pablo -- http://www.ousia.tk
