Scenarios aren't recognized if there aren't two newlines after the Feature: block

[pib]

The following feature has the first scenario treated as if it were the description of the feature:

Feature: demonstrate a bug
    Scenario: This one will be treated as the Feature description
        Step one

    Scenario: this one will be seen as a scenario
        ...

[pib]

This is easy enough to avoid by just putting an extra newline in there, but it could lead to some confusing situations, so it's best to fix it at some point.
