For those that are submitting language packs please remember that they can not contain any whitespace in the file and they also have to have a blank line at the end of the file.
They would cause an issue with phpBB2 and phpBB3.0.x due to the php files having an ending ?>. phpBB3.1.x no longer has those and can't have those so a blank line at the end of the file is necessary (and Travis builds will fail without it).
