        - Add "cxx" and "hxx" to the list of extensions that the
          "c-file" regexes apply to, and add "warning" and "error" to
          them as well. (Mike Frysinger)
+       - In the preprocessor directives regex string in the "c-file"
+         regexes, cover more whitespace characters than just " " by
+         using "[[:space:]]" instead. (Mike Frysinger)  DLR: Extend
+         this to other regex strings whenever possible.
+       - Move some overly long split-up regex strings that cover
+         similar areas onto the same line. (DLR)
 - nanorc.5:
        - Update the description of how the "color" regex works. (DLR)
        - Clarify descriptions of the characters that aren't allowed
