What if we have 2 projects with lib/test.dart and one of them uses another?
Will it set breakpoints in both lib/test.dart files?

[devoncarew, 2014/10/20 21:37:35]

Current behavior is that we set breakpoints for the current project, and any
breakpoints that might be packages breakpoints. In the above scenario, we should
set lib/test.dart, package:foo/test.dart, and package:bar/test.dart.
