Last sentence says printing its version, but `ruby --verbose` outputs nothing and quits.

Bug #14633: The behavior of command option `--verbose` is different from its help message

----------------------------------------
According to `ruby --help`, command option `--verbose` is

~~~
  -v, --verbose   print version number, then turn on verbose mode

~~~

But actually it doesn't show version number, and seems to turn verbose mode without any message.
I don't know its original intention, but currently its behavior is different its help message.

IMO, if the help message is wrong and the behavior is correct,  there're three similar options (`--version` just shows version number; `--verbose` just turns verbose mode; `-v` do both), so it's a little confusing.
