Long messages cause a confusing error

[Nick Heiner]

Using the following grunt config:

        attention: {
            'repro-bug': {
                options: {
                    message: 'this_is_a_very_very_very_very_very_very_very_very_very_very_very_very_long_message'
                }
            }
        },

and a small terminal window:

One gets the following unhelpful error:

Warning: Invalid array length Use --force to continue.

The error comes from this line:

function repeat(str, count) {
    // count is negative
    return new Array(count).join(str);
}

Great find, hope that wasn't blocking you. Bumped npm version to 1.0.0 to be on semver.
