In particular, I get warnings like this: tools/patman/../patman/commit.py:9: SyntaxWarning: invalid escape sequence '\s' re_subject_tag = re.compile('([^:\s]*):\s*(.*)') We should use a raw string (r'...') so that all escaping is passed into the regex module, not interpreted within the string itself.
