OK, I looked a bit at the code and here's a solution...

1. Bring back the Jam/MR code to add the command line targets for update

2. Change the UPDATE builtin to work like so:

UPDATE some_targets ; ## marks the given targets for update

UPDATE ; ## removes all targets from the update list

3. Change the Jambase so that it calls "UPDATE ;" in the case of bjam
functionality. In this way the need for the above "for" loop goes away.

If that sounds fine with all, I can go do this fairly quickly :-)
