same rule for is_unique when editing and adding entries

[eluser]keithics[/eluser]
the function only overrides that current is_unique method. that means you can use it the same way.

is_unique[users.username]

the primary key is automatically detected.

But as gte451f said, if you have Composite Primary Keys in your table, it wont work.
