1. Add a blank line to separate this method from the methods above, which form a
group ("SSLClientSocket implementation").

2. The Style Guide recommends naming this getter method "reached_connect",
matching the name of the corresponding data member. See

http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml#Function_Names

Also, it is usually defined inline:

  bool reached_connect() const { return reached_connect_; }

Done.
