Why would it? IMHO, neither of the two is really expected to be the
New or the Old file, and especially *not* in the case of context or
unified diffs. In both of these formats, the headers of a full diff
clearly indicate which of the two files any given new, removed, or
changed line came from.
The only cases where new vs. old really becomes importand are:
1) 'ed' style diffs
2) use of 'diff' output for feeding it into 'patch'
2) is covered by the relevant node in the full docs (info diffutils).

Sorry, but I fail to see how one of the two possible orders could be
more correct than the other, or more wrong.
