This make the transitions between case clearer.

Comparing with a merge with colliding rename
--------------------------------------------

- the "e-" branch renaming b to f (through 'g')
- the "a-" branch renaming d to f (through e)

  $ case_desc="merge with copies info on both side - A side: rename d to f, E side: b to f, (same content for f)"

  o  1 i-1: a -move-> c
  |
  o  0 i-0 initial commit: a b h
  


Merge:
- one with change to an unrelated file (b)
- one overwriting a file (d) with a rename (from h to i to d)

  |
  o  0 i-0 initial commit: a b h
  


Merge:
- one with change to a file
- one deleting and recreating the file

Unlike in the 'BD/DB' cases, an actual merge happened here. So we should

  o  1 i-1: a -move-> c
  |
  o  0 i-0 initial commit: a b h
  


Merge:
- one with change to a file (d)
- one overwriting that file with a rename (from h to i, to d)

Comparing with a merge with colliding rename
--------------------------------------------

- the "e-" branch renaming b to f (through 'g')
- the "a-" branch renaming d to f (through e)

  $ hg log -G --rev '::(desc("mAEm")+desc("mEAm"))'
  o    20 mEAm-0 merge with copies info on both side - A side: rename d to f, E side: b to f, (same content for f) - the other way

    b (no-filelog !)
  R a
  R b


Note:
| In this case, one of the merge wrongly record a merge while there is none.
| This lead to bad copy tracing information to be dug up.
