lint:yaml complains about a YAML file not being valid under certain circumstances since commit d83e346 by @paradajozsef

Example file:
https://github.com/liuggio/ExcelBundle/blob/excel-forks/Resources/config/services.yml

In this case the error message mentions line 91. The issue appears to be related to a commented line following an array. When a blank line is inserted after line 89, before the comment in line 90, the error message is gone.
