REVISION SUMMARY
  Earlier we were passing basename instead of the fullpath and then joining with
  the tmproot. This is wrong because the user can choose `rev1a` as wdir and in
  those cases, tmproot should not be joined with the path.
  
  I am working on refactoring extdiff logic so that we can have options like `diff
  --tool` and encountered this. Although this patch in itself makes no difference,
  however in future when a new caller of `_runperfilediff()` will be added, it
  will be useful to directly pass on the full paths instead.
