Heikki Linnakangas cb3384a0cb Fix output of ISBN-13 numbers beginning with 979. ... An EAN beginning with 979 (but not 9790 - those are ISMN's) are accepted as ISBN numbers, but they cannot be represented in the old, 10-digit ISBN format. They must be output in the new 13-digit ISBN-13 format. We printed out an incorrect value for those. Also add a regression test, to test this and some other basic functionality of the module. Patch by Fabien Coelho. This fixes bug #13442, reported by B.Z. Backpatch to 9.1, where we started to recognize ISBN-13 numbers.		2015-08-02 22:12:33 +03:00
