#13536: boost::lexical_cast<int>(" 1 ") can no longer handle whitespace
--------------------------------+-----------------------------
 Reporter:  maxim.egorushkin@…  |      Owner:  Antony Polukhin
     Type:  Bugs                |     Status:  new
Milestone:  To Be Determined    |  Component:  lexical_cast
  Version:  Boost 1.61.0        |   Severity:  Showstopper
 Keywords:                      |
--------------------------------+-----------------------------
 boost::lexical_cast can no longer handle whitespace when converting
 strings to integers:

 {{{
     #include <string>
     #include <iostream>
     #include <boost/lexical_cast.hpp>

     int main() {
         auto i = boost::lexical_cast<int>(" 1 ");
         std::cout << i << '\n';
     }
 }}}

 The above incorrectly throws an exception.

 The correct result of boost::lexical_cast<int>(" 1 ") is `1` and no
 exception.

 At least boost version 1.54 did not have this problem.
