How do I get HTML Tidy to not put newline before closing tags?

Question

HTML Tidy has this infuriating habit of putting a newline before the closing tag. For example:

Some text

<

Answer 1

Make sure vertical-space is set to no. After much frustration I learned the only thing that switch does is screw up your already somewhat-nicely formatted html by adding newlines where you don't want them.

This is what I use for minimally-invasive tidying (no adding doctypes/head tags, etc.):

tidy -mqi --doctype omit --show-body-only true --show-warnings no --vertical-space no --wrap 0
