If you are talking about the opening having a vertical slope between the end 
of the bottom and top lines, I haven't studied this but have generally 
observed the resemblance of it, rather than the opening being perpendicular 
to the hairpin direction. I don't know wether it is intended or not though 
since it seems in most of those examples that one line or the other was 
usually made longer, even on horizontal ones (nobody's perfect).

I thought that the hairpins were angled to fit tighter spaces, such as between 
two crowded staves, rather than to follow the change in pitch. I don't have 
any old sources showing consistency with any ideas here.

If it isn't a normal LilyPond option, I'd like to at least see how to tweak it 
to have the professional look; it's the LilyPond way and hopefully you guys 
know the right from wrong again.

Thanks again,
