[Koha-patches] [PATCH] Bug 6539: Creates a function to validate an isbn and uses it to populate the Z3950 search popup isbn with this value, the the value is not an isbn number the title field is populated.

[Frédéric DEMIANS]

A generic, and robust, Perl ISBN module is already used in Koha : 
Business::ISBN

   http://search.cpan.org/dist/Business-ISBN/

Please, use it rather than partially recoding it.
