title: BiBtex line break
body: <p>I edited an BibteX file and it works so far that it shows all information I need. </p>
  
  <pre><code>FUNCTION {electronic}
  { output.bibitem
    format.btitle "title" output.check
    url output
    format.date "year" output.check
    fin.entry
    empty.misc.check
  }
  </code></pre>
  
  <p>with</p>
  
  <pre><code>@Electronic{L2PwikiAAS,
    title     = {Wiki des L2P-Lernraumes},
    year      = {05.12.2016},
    url       = {https://~/collaboration/Lists/WikiList1/Atomabsorptionsspektroskopie%20(AAS).aspx},
  }
  </code></pre>
  
  <p>but the URL is very long and it goes over the end of the page.</p>
  
  <p>What should I do to get a linebreak somewhere in this URL?</p>
  
  <p>And how can I add the string 'Zuletzt aufgerufen am:' before the date?</p>
  
  <p>Thanks in advance</p>
