Re: [PATCH 1/1] range-diff: internally force `diff.noprefix=false`

Johannes Schindelin [off-list ref] writes:

While at it, I invert the logic in v2: instead of forcing a prefix, I
now force no prefix (and reduce the strip level from 1 to 0 when parsing
the diff header).

Ah, that approach would also work and may be conceptually cleaner
than requiring a/ and b/ prefix and forcing them.
