I don't understand this part. Do you mean rendering on GitHub? What inconsistency do your newlines fix...?

When viewed in a text editor with word wrap off, every line but the ones I changed are manually wrapped at ~80 chars, and stuck out significantly. The missing backticks were causing text that was intented to be monospaced to not be.

Thanks. Personally, I don't feel this is a problem, but this seems harmless to merge.

The missing backticks are definetely what needs to be fixed. Thanks for catching this!
