Comment(by gsathya):

 ACK! I just saw that you passed Multiple=True to Config.get_value(), in
 your latest commit.  Now with the above example, when we call
 Config.save() we'd be storing
 {{{
 login.password foo bar
 }}}
 Right?

 Now, if we were to read that file again
 {{{
       user_config = stem.util.conf.get_config("relogin")
       user_config.load("/home/foo/myConfig")

       user_config.get("login.password")
       #The password becomes "foobar" which is wrong!
       #This is because we strip out all the whitespaces
       #after the first whitespace and store them as the
       #value.
       #key, value = line.split(" ", 1)
 }}}
