I think the script might break when we reach r10⁷ (r10000000) because
"svn mergeinfo"'s output is sorted numerically, but comm(1) expects its
inputs to be sorted according to strcoll(3).

Currently comm(1)'s precondition does hold, but only because all the
revision numbers in "svn mergeinfo"'s output have the same number of
digits. However, as soon as HEAD passes a power of ten, we'll run into
the problem that "r9" is printed before "r10" (because 9 < 10) but
«!(strcoll("r9", "r10") < 0)». (This is the same problem we warned
about in the 1.9 and 1.10 release notes.)

Would that need new RA APIs?
