2260,Missing slash when iterating windows root path,Lin Yi-Li <record.nctu.cis91@…>,Beman Dawes,"A windows root path without backslash or slash, ex. ""C:"", will cause the result of directory_iterator missing a slash after ':'.
For example, it will produce a broken path such as ""C:filename"".

Here is a sample to produce this:
{{{
#include <iostream>
#include <locale>
#include <boost/filesystem.hpp>

using namespace boost::filesystem;

int main() {
	const char *drive_to_search = ""C:"";
	std::cout.imbue( std::locale());

	for( directory_iterator i( path( drive_to_search, native)), end; i != end; ++i) {
		std::cout << i->path() << std::endl;
	}

	return 0;
}
}}}

By tracing the stack, I think the problem is function boost::filesystem::basic_path<std::basic_string<wchar_t,std::char_traits<wchar_t>,std::allocator<wchar_t> >,boost::filesystem::wpath_traits>::m_append_separator_if_needed() won't append a slash in case of merging windows root path and filename.

Here is the call stack starting at the constructor of directory_iterator.
