Given the nature of ANT, I think it may be really important to be able
to specify super in the dependencies of the overriden method.
I think part of the problem on this issue i that we have been trying
too hard to use rewriting as oppose to simply say what we want.

For example, we could write something like:

<target name="a" depends="b,c" apply-super-after="b"/>

and we could have an "apply-super-before" or simply "apply-super-first" attribute.
That is all that is needed to have super in dependencies, the ordering 
of targets will occur automatically by the engine.

No need for rewrites, This could be done in <override-target> instead
which to me is just a specialized form of target.

In my opinion, <antcall> should apply on the entire top-level
build file. Just as executing ant.cmd would do. That has been
the meaning of it and I do not think we need to overloaded
with a direfent meaning.

If you want to execute a local target use <ant> passing the local file.
