const std::string return value results in pessimization

[kauboy26]

Hi,

I was taking a look at path.hpp and found that some functions, such as path::string(), returned by value but were marked as const.

So for example, if I had a path object path1, and then I made a std::string object s as follows:

std::string s = path1.string();  

The above would call std::string's copy constructor rather than its move constructor.

I was wondering if this was intended behavior, as we are missing a chance to optimize.

Thank you!

Thanks for the report.
