Bad error reporting.

[floitschG]

When a syntax error is detected the VM prints a list of library-imports first.
Since the error-buffer seems to be limited to some arbitrary limit the real error is often not shown.
Example:
===
$ cat bug1.dart

library("bug1");

import("bug2.dart");

$ cat bug2.dart

library("bug2");

import("bug3.dart");

$ cat bug3.dart

library("bug3");

abstract class A { }
$ out/Release_ia32/dart bug1.dart
'/tmp/bug1.dart': Error: line 2 pos 1: library handler failed: '/tmp/bug2.dart': Error: line 2 pos 1: library handler failed: '/tmp/bug3.dart': Error: line 3 pos 1: unexpected token 'abstract'
abstract class A { }
^

import("bug3.dart");

^

import("bug2.dart");
