Change output of test.dart --list option, so it can be parsed automatically.

Change output of test.dart --list option, so it can be parsed automatically.

The framework that lets shared tests be run in Eclipse uses the output of this command, and this framework is tested when running test.dart --component=dartc dartc/junit_tests.

This is not quite satisfactory yet - it hasn't been tested in Eclipse, and I
can't find out what lines are failing the assert, that is now changed to a

Let's look at this together when I'm back in the office.

OK, comments are addressed.  This should be fine to commit - it is tested, and
works.
