225    2006-08-30  Martin Maechler  <maechler@stat.math.ethz.ch>
226    
227            * R/dgCMatrix.R: aargh: "Arith(<dgC>, numeric)" was wrong because
228            of a 0-index which was used as 1-index (..hmm)
229    
230            * R/sparseMatrix.R (prSpMatrix): fix printing an all-0 sparse Matrix
231    
232            * R/Auxiliaries.R (all0, is0): for 0-testing in presence of NA's
