Quality prevails over compatibility when the quality gain is deemed to 
exceed the problems incurred by losing compatibility.

In this case, do-while works just fine. Lots of people are used to using it 
and have never even heard of repeat-until, having never used Pascal or any 
other language that used it. At this point, C's influence far outweights 
Pascal's.

Also, AFAIK, do-while is not generally a major source of bugs. As such, 
while another construct might be better, since the current one isn't much of 
a problem, it's not worth breaking compatibility. If it were shown that do-
while was a big problem, then it might be. But at this point, do-while works 
just fine, so it's not worth changing it.
