[PATCH v2 1/2] .gitinogre: update the command to check tracked files being ignored

[Masahiro Yamada]

Recent git versions do not accept the noted command.

  $ git ls-files -i --exclude-standard
  fatal: ls-files -i must be used with either -o or -c

The -c was implied for older git versions, but we need to make it
explicit now.

Also, replace --exclude-standard with --exclude-per-directory=.gitignore
so that everyone will get consistent results.

git-ls-files(1) says:

  --exclude-standard
      Add the standard Git exclusions: .git/info/exclude, .gitignore in
      each directory, and the user's global exclusion file.

We never know what are locally added to $GIT_DIR/info/exclude or
$XDG_CONFIG_HOME/git/ignore.

We can only manage .gitignore files committed in the repository.
