Markdown line hard-wrap discrepancy in v2.0

[renemarc]

Before v2.0 gets adopted too widely, I propose that the markdown version be hard-wrapped to 80 characters like v1.4 mostly was.

Currently in v2.0 a few lines are wrapped at 80, but most are not.

Advantages of wrapping at 80 columns:

• Makes using a text-editor and/or multiple windows on a modern screen easier.
• Matches the style for health files like LICENSES and other text files.
• Doesn't clash with many style guides for accompanying code (PHP/Java at 80, Python at 79, Ruby at 100).
• Helps to bring consistency to any project's code-base.

Furthermore, Markdown parsers will follow the original standard and treat hard-wraps like a space, so wrapping lines will be transparent to readers.

A PR to address this issue follows shortly.
