389            make tril(), triu(), band() work for "matrix" and all "dense*"
390    
391            * R/triangularMatrix.R (.tri[lu].tr): need .diagU2N(*)
392            * tests/simple.R: test the fix above
393

410            * R/Tsparse.R (.TM.sub.i.2col, .TM.repl.i.2col): ditto;
411                    now, M[lower.tri(M)] and  M[lower.tri(M)] <- v  work better
412

414            * src/Tsparse.h, init.c: ditto
415            * R/Auxiliaries.R (isTriT): new; faster than going via Csparse

451            * R/CHMfactor.R (solve): method for b="numeric", but also b="ANY"
452                    in order to ensure 'system = *' is not lost;
453                    formals()$system instead of cut&paste.
454            * tests/factorizing.R: test solve(<CHM..>, <numeric>)
