[PATCH 1/1] doc: short overlong title underlines

Heinrich Schuchardt heinrich.schuchardt at canonical.com
Sat Oct 28 12:03:12 CEST 2023 

Title underlines should match the length of the title. Unfortunately
docutils only catches underlines that are too short.

Add some missing empty lines after titles.
