minErr: Make optional link on errors.angularjs.org

[maksimr]

It's useful when you write tests and output tests' result to terminal.
On small displays query parameters for errors.angularjs.org occupy a large part of display and you have to switch to screen where run tests and scroll to the beginning of the error message.

That doesn't seem unreasonable, although I am not sure how you would tell minErr to not append the whole stack.

Running into this problem myself. As a workaround I'm piping test output through grep

grunt test | grep -v http://errors.angularjs.org

@phdesign I followed your advice, but just realized this is not a very good solution for most usages.

I put this into my package.json to have npm test:

"scripts": {
  "test": "karma start --single-run | grep -v errors.angularjs.org"
}

Normally, when you run the test (karma start --single-run) and it fails, karma exits with non-zero exit code.

However when you pipe to grep, the exit code will be 0 even it failed! So suddenly all the tools, like build hooks that relied on npm test to return zero only for good tests (and non zero when there are issues, to immediately stop the build) are broken
