It's in the commit log. :-)

The function ident_zeros inserts 1 in the diagonal in all rows where
all entries are zero. This can be used to constrain inactive dofs.

The best option for this would be to implement support for restricted
function spaces (where dofs in some regions are inactive) but it's
currently broken.
