 For each pathname given via the command-line or from a file via
-`--stdin`, show the pattern from .gitignore (or other input files to
-the exclude mechanism) that decides if the pathname is excluded or
-included.  Later patterns within a file take precedence over earlier
-ones.
+`--stdin`, check whether the file is excluded by .gitignore (or other
+input files to the exclude mechanism) and output the path if it is
+excluded.
 
 By default, tracked files are not shown at all since they are not
 subject to exclude rules; but see `--no-index'.
