gnome-terminal forks even with `--disable-factory`

[Cyprian Guerra]

Manual states:

--disable-factory
    Do not register with the activation name server, do not re-use an
    active terminal.

Yet terminal opens and "foo" is being printed immediately even though the terminal didn't close:

$ gnome-terminal --disable-factory; echo foo
foo
```

This behavior was different in the past and doesn't seem "normal" for a Linux application, e.g. it now prevents using gnome-terminal as a `vim` wrapper for an external editor. Usually Linux applications are manually forked with ampersand and as far as I understand it still should be possible with a `--disable-factory` argument.

Seems to be working in GNOME Terminal 3.18.2. Current manual misses this description entirely, I wouldn't know if I didn't try.
