On the second line after formula (16) replace "This system is uniquely solvable"
by "This system is uniquely solvable except if $e_4=q^2$.

On the line above formula (98) replace "(1-q^n)E_{n-1}" by "(1-q^n)R_{n-1}".

On p.450 in the journal version or on p.25 in the arXiv version replace in the
last line before subsection 5.5
$qa,b,c,d$ by $q\tilde a,\tilde b,\tilde c,\tilde d$.
