Don’t break right after an HTML code tag that’s followed by a literal

[now]

If a CODE_OPEN_TAG token is followed by a LITERAL token, break before writing the CODE_OPEN_TAG token if writing it will result in us eating up the remainder of the current line.

Partially fixes #84.

I’m not super happy about the breakBeforeIfAtEndOfLine name, but that’s the best I could come up with right now. I also wish there was a cleaner way of peeking at the next token.

Could someone please have a look at this? Thanks!
