[reese]

On rust nightly/beta, this is now a clippy violation, so I figured I'd just preemptively fix it

error: this `if` guard returns a bool literal and is followed by another

(The suggestion was !(context == FormattingContext::ClassOrModule && !original_used_parens), but that was a double-negative so I made it context != FormattingContext::ClassOrModule || original_used_parens instead.)
