Really? I thought that the pipe character is the separater. Means, that 
if I have

   lib.sidemenu.stdWrap.ifEmpty.wrap = <div id="nothing"> | </div>

the pipe means something different than like this:

   lib.sidemenu.stdWrap.ifEmpty.wrap = |

Interesting. and... confusing... But good to know.

Thanks, man!
