See test documentation for details. This is yet another corner case for copy
tracing.

  $ hg up null --quiet

Merging a branch where a rename was deleted with a branch where the same file was renamed
------------------------------------------------------------------------------------------

Create a "conflicting" merge where `d` get removed on one branch before its
rename information actually conflict with the other branch.

(the copy information from the branch that was not deleted should win).

  $ hg up 'desc("i-0")'
  3 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg mv b d
  $ hg ci -m "h-1: b -(move)-> d"
  created new head

  $ hg up 'desc("c-1")'
  1 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ hg merge 'desc("h-1")'
  1 files updated, 0 files merged, 1 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg ci -m "mCH-delete-before-conflict-m-0"
