Issue Description:

Formatting with `prioritizeKeepingFunctionOutputTogether` engaged can lead to assertion failures.

This code is enough to trip it:

init(a: B) {}

I get this error too even when setting:

prioritizeKeepingFunctionOutputTogether: false

using swift 5.5.2 + swift-format 0.50500.0 on ubuntu

EDIT:

Found a different culprit:
rules: { BeginDocumentationCommentWithOneLineSummary: true }
