Re: Crescendo hairpin colliding with repeat bar line

Do you mean an override like mine should become the default? Maybe, yes. 
I have some other work high on my priority list (there's a certain 
larger pending merge request...), but I could at least to a regression 
test run and see what such a change would effect globally.

The reason is that I liked the reduced distance between hairpin and 
barline in the '|' case:

I thought this looked better than the version with global (LEFT . LEFT) 
setting:

But the difference is admittedly tiny, and maybe I was wrong in the 
first place.

It probably played a role that the situation "hairpin stopping at | 
barline" is very common and well-tested in LilyPond, so I deemed it 
improbable that a carefree change of it made by me should be an 
improvement in that case.
