[PATCH 0/3] checkout: fix two bugs on count of updated entries

This fixes two issues at the "Updated %d path from the index" report at the end of a `git checkout <paths>` operation:

  - Delayed checkout entries being counted twice.
  - Failed entries being included in the count.

The first two patches add tests and the third implements the fix. I came across this while working at parallel checkout, but only managed to get back to it now.

  checkout: document bug where delayed checkout counts entries twice
  checkout: show bug about failed entries being included in final report
