Update of /cvsroot/monetdb/MonetDB5/src/modules/kernel In directory sc8-pr-cvs16.sourceforge.net:/tmp/cvs-serv28347/src/modules/kernel
Modified Files: batcalc.mx batifthen.mx group.mx kprelude.mx Log Message: batifthen.mx: use (fast) direct assignments instead of bunfastins for ifthenelse (not for ifthen as it can be small as the input bat) group.mx: return read only bats.

basic questions: is it correct that the input's heads are no longer used in CMDifThenElseCst2_@1(), while they are (still) used in CMDifThenElseCst_@1(), CMDifThenElse_@1() & CMDifThenElseCst1_@1() No in this fall back case all should still use the head. I'll check in a fix shortly.
