checkout: fix two bugs on the final count of updated entries
At the end of `git checkout <pathspec>`, we get a message informing how many entries were updated in the working tree. However, this number can be inaccurate for two reasons: 1) Delayed entries currently get counted twice. 2) Failed entries are included in the count. The first problem happens because the counter is first incremented before inserting the entry in the delayed checkout queue, and once again when finish_delayed_checkout() calls checkout_entry(). And the second happens because the counter is incremented too early in checkout_entry(), before the entry was in fact checked out. Fix that by moving the count increment further down in the call stack and removing the duplicate increment on delayed entries. Note that we have to keep a per-entry reference for the counter (both on parallel checkout and delayed checkout) because not all entries are always accumulated at the same counter. See checkout_worktree(), at builtin/checkout.c for an example. Signed-off-by: Matheus Tavares <matheus.bernardino@usp.br> Signed-off-by: Junio C Hamano <gitster@pobox.com>
