The pieces ('segments') of a way still have to remain contiguous so, 
yes, if you did this you would have to split, and I think this could be 
two step, ust as you;d do it now (split in two places and then delete 
the divided part)

However, the common case I keep coming up against is wanting to remove 
the last segment, particularly where it joins another one. This is 
easier, and it may be useful to have a one step operation for this. Not 
that you can't do it already, it's just a combination of operations I 
keep on doing.

R = want to remove this first or last segment. This doesn't require 
splitting or changing nodes other than when there is no connecting way, 
when the trailing node could go too.
