+Use this option to specify files that syntastic should neither check, nor
+include in error lists. It has to be a list of |regular-expression| patterns.
+The full paths of files (see |::p|) are matched against these patterns, and
+the matches are case sensitive. Use |\c| if you need case insensitive
+patterns. >
