Fixed whitespace issues

[rr-]

• Removed trailing whitespace
• Fixed legal notice formatting inconsistency

Trailing whitespace, on top of being a bad practice, slow down vertical movement in editors such as vim which use blank lines as jump markers.

Thanks, although I personally never had any issues with trailing spaces. They're usually caused by the auto-formatting of my IDE, which puts the indention of the previous line into the next.
