Hairpins ending on key changes

[Connor Harris]

In Lilypond 2.18.2 and possibly later versions, hairpins that end at the 
beginning a measure are engraved with their right ends slightly left of 
the barline. This looks bad if the note follows a key change, as there may 
be considerable space (depending on how many accidentals are notated in 
the key change) between the barline and the note on which the hairpin 
properly ends. In this fragment, I'd prefer the hairpin to continue all 
the way to the dynamic marking under the second note.
