I can't think of a situation in computing where we use an
exclusive-first.  Pure mathematics, yes, we might want to express a
range as (1,2) to exclude both 1 and 2 but include 1+epsilon for all
epsilon > 0.  Maybe I don't work with floating point numbers enough,
but I've never seen a kernel programmer make an off-by-one with the
start of a range.  End-of-the-range is all too common.
