[Request] [+ ] D12432: rust-dirstatemap: correctly decrement the copies counter

[Alphare (Raphaël Gomès)]

Alphare created this revision.
Herald added a reviewer: hg-reviewers.
Herald added a subscriber: mercurial-patches.

REVISION SUMMARY
  This was caught when writing unit tests for the `DirstateMap`. We were always
  setting `had_copy_source` to `false` since we erased the value just before.

REPOSITORY
  rHG Mercurial

BRANCH
  stable
