Template for formatting ISBN-13 numbers. Hypens and spaces are stripped out at the start.
The format for ISBN-13 is
[978/979]-[region]-[publisher]-[title]-[checkdigit]
the region is a fixed length (depending on where it came from), but the publisher and title fields can be any length, so they're currently grouped together.
Examples
{{FormatISBN13|978-4073055501|link=yes}}
{{FormatISBN13|9785073 055501}}
978-50-73 0555-01
