'svnadmin load' -- or, libsvn_repos's load-fs-vtable.c code, at least --
implements a mapping from revisions found in the dumpstream to actual revisions
in the repository, which is useful for correcting copyfrom revisions and maybe
some other things (mergeinfo? I can't recall...) when loading into a non-empty
repository or other scenarios where revision N in the source repository (from
which the dump cometh) and revision N in the target repository (to whence the
dump goeth) aren't the same revision.
'svnrdump load' doesn't do that. Result? Brokenness.
