Yes. We strip the spaces because we now preserve format=flowed in the
Content-Type: header, but we don't want to flow the footer. But, we
went too far in stripping the space from a signature leadin.

Change the "text =" line above to

        text = re.sub(r'(?m)(?<!^--) +(?=\n)', '',
                      re.sub(r'\r\n', r'\n', template % d))

This fix has been committed for the next release.
