Indeed it's trivial (convert on input every line ending to a unique form that 
could be at best unicode <LINE SEPARATOR> not to be accused of bias ;-), then 
convert back to the current Os's form on output). Tons of PLs do that 
transparently. I also cannot understand why any tool in the XXIth century does 
not provide this feature (without even mentioning it, so trivial an issue it 
is). Even less /programmer/ tools like git! Where's the point?
