biblio.C: another parsing bug

[Juergen Spitzmueller]

Herbert,

The following entry is parsed wrong in the citation dialog (as "Reichardt, 
Rolf, {" and nothing more), This happens to all my entries where I use two 
commas as opening quotation marks (I use this in pybliographer, because it's 
the only way to insert german opening quotation marks without fiddling in 
advanced editing mode). I guess biblio.C misinterprets the comma as an entry 
separator.

Juergen.
