Crescendi overlapping bars, should be able to stop at first note after the bar

[gringer]

Hello,

I've noticed some odd behaviour with the location of crescendi where they
overlap a bar and end one note after the bar. In the code I have provided, 
there are six crescendi, here's where I expect them to start/end:

1) Starts on the left of the e, ends on the right of the c [actually barline]
2) Starts on the left of the d, ends on the right of the e [correct]
3) Starts on the left of the d, ends left/middle of the c [actually barline]
4) Starts right/middle of the c [actually left of the c], ends on the right of
   the e
5) Starts left of the c, ends left/middle of the d [correct]
6) Starts right/middle of the d, ends right of the e [correct]

What I'm seeing here is something that seems like a strange rule to me:
crescendi only stop on a barline when they are meant to stop one note after 
the barline. Is there a way I can get these to line up properly with the 
correct notes?

Cheers,

Here is some code to reproduce this bug:

\paper {
  #(define dump-extents #t)
  
  indent = 0\mm
  line-width = 160\mm
  force-assignment = #""
  line-width = #(- line-width (* mm  3.000000))
}

\layout {
  
}
