When parsing the diffs, `range-diff` expects to see the prefixes `a/`
and `b/` in the diff headers.
If so, passing src/dst prefix as command line option is a much
better solution, I think. diff.noprefix may not stay to be (or it
may already not to be) the only thing how the prefix gets chosen.
That is, "--src-prefix=a/ --dst-prefix=b/", so that configuration
variables yet to be invented for setting prefixes different from a/
and b/ can also be overridden, not just diff.noprefix (ancient Git
used l/ and k/ as src and dst prefix, IIRC).
