3            * R/Matrix.R (.M.sub.i.2col): fix for logical matrix indexing
4            * R/Tsparse.R (.TM.sub.i.2col, .TM.repl.i.2col): ditto;
5                    now, M[lower.tri(M)] and  M[lower.tri(M)] <- v  work better
6    
7            * src/Tsparse.c (Tsparse_to_tCsparse): new fast utility.
8            * src/Tsparse.h, init.c: ditto
9            * R/Auxiliaries.R (isTriT): new; faster than going via Csparse
10                 both isTriC() and isTriT() now return TRUE with "kind" or FALSE.
11            * R/sparseMatrix.R (isTriangular): hence simplified

15          * R/Ops.R (.Arith.Csparse): new utility factored out of former          * R/Ops.R (.Arith.Csparse): new utility factored out of former
