// TODO: See T1702. When viewing the versus diff of diffs, we may
// have files with the same filename. For example, if you have a setup
// like this in SVN:
//
// a/
// README
// b/
// README
//
// ...and you run "arc diff" once from a/, and again from b/, you'll
// get two diffs with path README. However, in the versus diff view we
// will compute their absolute repository paths and detect that they
// aren't really the same file. This is correct, but causes us to
// throw when inserting them.
//
// We should probably compute the smallest unique path for each file
// and show these as "a/README" and "b/README" when diffed against
// one another. However, we get this wrong in a lot of places (the
// other TOC shows two "README" files, and we generate the same anchor
// hash for both) so I'm just stopping the bleeding until we can get
// a proper fix in place.
