Test to make sure folding renames doesn't cause bogus conflicts (issue4251):
  $ hg init issue4251
  $ cd issue4251

  $ mkdir initial-dir
  $ echo foo > initial-dir/initial-file
  $ hg add initial-dir/initial-file
  $ hg commit -m "initial commit"

Move the file to a new directory, and in the same commit, change its content:
  $ mkdir another-dir
  $ hg mv initial-dir/initial-file another-dir/
  $ echo changed > another-dir/initial-file
  $ hg commit -m "moved and changed"

Rename the file:
  $ hg mv another-dir/initial-file another-dir/renamed-file
  $ hg commit -m "renamed"

Now, let's try to fold the second commit into the first:
  $ cat > editor.sh <<EOF

  > pick b0f4233702ca 0 initial commit
  > fold 5e8704a8f2d2 1 moved and changed
