For future reference the answer is to edit /etc/login.defs and change:
CHARACTER_CLASS
[ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz_]
[ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789_.-]*[ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789_.
$-]\?
to
CHARACTER_CLASS
[ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789_.-]*[ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789_.
$-]\?
ie. delete the first regexp block.
Thanks to Henne for the correct answer and to Andreas and Thorsten (albeit
after I had solved the problem) who both pointed me in the direction of the
correct man page.
Cheers
