  63         // like this in SVN:
  64         //
  65         //  a/
  66         //    README

  70         // ...and you run "arc diff" once from a/, and again from b/, you'll
  71         // get two diffs with path README. However, in the versus diff view we
  72         // will compute their absolute repository paths and detect that they
  73         // aren't really the same file. This is correct, but causes us to
  74         // throw when inserting them.
  75         //
  76         // We should probably compute the smallest unique path for each file
  77         // and show these as "a/README" and "b/README" when diffed against
  78         // one another. However, we get this wrong in a lot of places (the
  79         // other TOC shows two "README" files, and we generate the same anchor
  80         // hash for both) so I'm just stopping the bleeding until we can get
  81         // a proper fix in place.
