Copy a file, then delete destination, then copy again. This does not create a new filelog entry.

  $ newrepo

  $ echo x > x

  $ hg ci -Aqm 'add x'

  $ hg cp x y

  $ hg ci -m 'copy x to y'

  $ hg rm y

  $ hg ci -m 'remove y'

  $ hg cp -f x y

  $ hg debugp1copies -r 3

  x -> y

  $ hg debugpathcopies 0 3

  x -> y

Copy x to y, then remove y, then add back y. With copy metadata in the changeset, this could easily

end up reporting y as copied from x (if we don't unmark it as a copy when it's removed).

  $ newrepo

  $ echo x > x

  $ hg ci -Aqm 'add x'

  $ hg mv x y

  $ hg ci -m 'rename x to y'

  $ hg rm y

  $ hg ci -qm 'remove y'

  $ echo x > y

  $ hg ci -Aqm 'add back y'

  $ hg l

  @  3 add back y
