#4030: read_graphviz() reads too much

 The way the code is currently written (lexing with Boost.Regex) does not
 lend itself to using istream_iterators or anything that would easily allow
 the use of files directly. Boost.Regex and Xpressive require
 bidirectional iterators, and the wrapper in Spirit can only turn
 istream_iterators into forward iterators. There is a previous version of
 the Graphviz parser that uses Spirit; you can enable it by #defining
 BOOST_GRAPH_USE_SPIRIT_PARSER (in r60770 and above, so please update). It
 has some bugs in parsing various parts of the Graphviz grammar, but you
 are not likely to hit them.
