Document that Space skip parser doesn't skip trailing spaces

[OlafvdSpek@…]

The documentation should mention that the space skip parser does not skip trailing spaces and the examples should be augmented to include the work arounds.

​http://svn.boost.org/trac/boost/ticket/3086

#include <cassert>

#include <boost/spirit/include/classic.hpp>

using namespace BOOST_SPIRIT_CLASSIC_NS;

int main()
{
    parse_info<> result = parse(" 5 ", int_p, space_p);
    assert(result.full);
    return 0;
}

[Hartmut Kaiser]

That's by design. If you need post-skipping you need to modify your grammar (appending eps_p forcing a post_skip to occur):

int_p >> eps_p;

BTW: in Spirit 2.1 we exposed this as an explicit parameter to parse.

He isn't asking for it to be fixed, he's asking for it to be documented, as he was advised to do in #3086.

We won't go back to this documentation as it refers to an absolutely outdated version. Please switch to the newer versions of Spirit.
