In the RC branch that is not the case. We need to keep the BBv1
available in HEAD so that we can do comparisons between them. Although I
guess we could add a "--v1" in HEAD, but perhaps it's not worth the effort.

Which follows what BBv1 does. But maybe that's not a good thing seing as
one was very unlikely to use an unversioned toolset.

I think we need to make this consistent across toolsets. AFAIR we've
always preferred using the most recent toolset version.

Don't know what those are about.

Except for the auto-detected toolsets the version is entirely up to the
user. This is true in both the command line and in the user-config.jam.
