fail-fast "PASSES M out of N tests" output is insufficient

[apjanke]

When you run plain test or test2, fail-fast behavior is the default.

But the non-verbose output for test2 in this case isn't sufficient; it doesn't make it clear that the test run was aborted.

>> test2 isosurface
PASSES 20 out of 21 tests
>>

That sounds like there were 21 tests total in the file, and only one of them failed. But there are actually at least 30 tests.

Add some additional output there: a line saying "test run aborted", and probably the detailed output for the failed test block.

Better:

>> test2 isosurface

*****  testify.internal.BistBlock: error (index=25)
  is_test=1  is_xtest=0
  error_id=''
  pattern=/Y must match the size of V/
Code:

 y = -14:6:11;
 fvc = isosurface (x, y, z, val, iso);
  -> success=0, msg=!!!!! Incorrect error raised: expected error message matching /Y must match the size of V/, but got 'isosurface: X must match the size of V'
Aborted test run due to test failure.
