* Document the colon-separated ``node[:port[:compass]]`` format used for ``tail`` and ``head`` points in the ``edge()``- and ``edges()``-methods' * Improve handling of escaped quotes (``\"``). Different from other layout engine escapes sequences such as ``\l`` and ``\N`` (which are passed on as is by default), there is no use case for backslash-escaping a literal quote character because escaping of quotes is done by this library. Therefore, a backslash-escaped quote (e.g. in ``label='\\"'``) is now treated the same as a plain unescaped quote, i.e. both ``label='"'`` and ``label='\\"'`` produce the same DOT source ``[label="\""]`` (a label that renders as a literal quote). Before this change, use of ``'\\"'`` could break the quoting mechanism creating invalid or unintended DOT, possibly leading to syntax errors from the rendering process.
