This new patch set eliminates all regtest diffs via a mechanism that allows extremal lyrics to be flush with the left edge. It kinda sorta bends LilyPond into doing something it is not designed to do :: returning pureY-extents for items that are dependent on the start and end positions (normally, only spanner Y-extents change based on start and end positions). The logic is that a LeftBarStub should have a Y-extent iff it is at the beginning of a staff and if said staff will not bump into a SystemStartBar. Knowing if it will bump into a SystemStartBar can only be done if we know which staves are alive and which staves are hara-kiri'd, which'll change based on the start / end in question.
This seems like the sorta thing that'd slow down lilypond, so I'd appreciate it if people tested it on pieces with lots-o-lyrics!
