Yes of course I knew this  way, but as we have talked about consistency
recently,  I think that $coeff is supposed to return always a matrix, even
1x1.  That is because with multiple regressors $coeff is the matrix of
coefficient, whereas with only one regressor it would the scalar of
coefficient. Moreover there is at least one case when I cannot know if the
regressors will be either single or multiple: that is when I have a
user-defined list of regressors.
Anyway this is just my opinion about a really negligible issue.
