Extend all hairpins over time signature changes

[N Trocado]

I like to have hairpins cut through barlines, extending to the note that ends 
them on the first beat of the next bar, whenever there's a time signature 
change. Stopping short of the barline in this case, as is the default, leaves a 
bit too much space between the end of the hairpin and the dynamic symbol.
I know that I can \override Hairpin.to-barline = ##f. But would it be possible 
to configure the default behavior to work as described, instead of spraying 
overrides everywhere?
