I tried commenting on an answer, and all of my paragraphs were strung together in a single paragraph.
I used proper markdown, adding two spaces at the end of each paragraph. When that didn't work, I tried appending a
<br/> to the end of my paragraphs, but that didn't work either! (In fact, the
<br/> was rendered in my answer, instead of being interpreted as HTML.)
What was I doing wrong?
If it's relevant, my comment can be found here: Can a Mac's model year be determined with a Terminal Command?
