template <class Path> bool remove(const Path& p, system::error_code & ec = singular );
    *  if ec != singular, then ec.clear().

I can't find any definition for 'singular'.  What is it?  Besides acting as a flag to know if the argument was defaulted, it seems like it's doing some kind of one-shot behavior?
