Use string_file::release in some places
I found a few spots like:
string_file f;
std::string x = f.string ();
However, string_file::string returns a 'const std::string &'... so it
seems to me that this must be copying the string (? I find it hard to
reason about this in C++).
This patch changes these spots to use release() instead, which moves
the string.
