Python strings have their own notion of backslash-escaping, and that can conflict with the intentions for strings passed to the 're' module. 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.
