* NOTE! We expect "a ^b" to be equal to "a..b", so we
* reverse the order of the objects if the second one
* is marked UNINTERESTING.
* NOTE! We expect "a..b" to expand to "^a b" but it is
* perfectly valid for revision range parser to yield "b ^a",
* which means the same thing. If we get the latter, i.e. the
* second one is marked UNINTERESTING, we recover the original
* order the user gave, i.e. "a..b", by swapping the trees.
