check-ignore currently shows how .gitignore rules would treat untracked
paths. Tracked paths do not generate useful output. This prevents
debugging of why a path became tracked unexpectedly unless that path is
first removed from the index with git rm --cached <path>
This option (-i, --ignore-index) simply by-passes the check for the path
being in the index and hence allows tracked path to be checked too.
Whilst this behaviour deviates from the characteristics of git add and
git status its use case is unlikely to cause any user confusion.
