#11898: Input stream operator of a filesystem::path can't handle spaces
------------------------------+------------------------
 Reporter:  anonymous         |      Owner:  bemandawes
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  filesystem
  Version:  Boost 1.58.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+------------------------
 The operator>> in filesystem::path breaks at spaces as it would for a
 std::string, whereas spaces can be an integral part of a path. Concretely,
 the following code
 {{{
 boost::filesystem::path p;
 std::istringstream("path/with spaces") >> p;
 std::cout << p << std::endl;
 }}}
 prints "path/with" on OS X 10.11.2. I believe boost::io::quoted is
 supposed to take care of the spaces in the operator>> implementation
 {{{
 is >> boost::io::quoted(str, static_cast<Char>('&'));
 }}}
 but this doesn't work on my system. (One of the weird points seems to be
 that it gets called with two arguments, but its declaration requires three
 and I can't find a default argument declaration.) Replacing the
 implementation with
 {{{
 std::getline(is, str);
 }}}
 seems to work for me, but I have a feeling that this bypasses some of the
 necessary logic in boost::io::quoted.
