Browse source 
The checkstyle.py patch has a fault which it identified in itself when
updating the regex string.

  --- utils/checkstyle.py

  #105: : W605 invalid escape sequence '\+'
  +    diff_header_regex = re.compile('@@ -([0-9]+)(,[0-9]+)? \+([0-9]+)(,?[0-9]+)? @@')

  1 potential style issue detected, please review

This is documented further at:

Update the string literal prefix to declare a raw byte string for the
regex parser.
