Remove irrelevant reference to a "security best practice"

This change includes three things:

1. Removing note about omitting version number due to "security best practices" as not including a version number is actually more [security through obscurity](https://en.wikipedia.org/wiki/Security_through_obscurity) rather than any real security.
2. Removed the irrelevant Stallman reference.
3. Syntax highlighting.
