4702	replace_extension truncates path	cheesy4poofs@…	Beman Dawes	"I've recently switched all our code to filesystem v3 and added BOOST_FILESYSTEM_NO_DEPRECATE on our builds for good measure.  One of the changes I had to fix was our use of change_extension(), which was modified to use the replace_extension() method.  However, some of our code started failing and I tracked it down to this example:

	boost::filesystem::path p(""C:\\database\\test\\filename"");
	p.replace_extension("".db"");
	std::cout << p.string() << std::endl;
	// OUTPUT - C:\database\test\filename.db

	p = ""C:\\database.1\\test\\filename"";
	p.replace_extension("".db"");  // bug?
	std::cout << p.string() << std::endl;
	// OUTPUT - C:\database.db

As you can see, in the second example, it truncates the path and assumes the directory name ""database.1"" has the extension that needs replacing.  change_extension() did not behave this way.

Is this the expected behavior?
