The following V2 Jamfile produce two separate lines of output:

make a : Jamfile : $(__name__).doit ;

actions doit
{
echo foo
echo bar
}

Are you sure you don't do something with the JAMSHELL variable somehow? It's 
not set by default, and that will cause the action body to be passed to 
shell, which can handle newslines just fine.
