While testing against PG12 I noticed the documentation states that
recovery targets are not valid when standby.signal is present.
But surely the exception is recovery_target_timeline? My testing
confirms that this works just as in prior versions with standy_mode=on.
Documentation patch is attached.

Subject: [PATCH] Add timeline as valid recovery target in standby.signal
documentation.
The documentation states that no target settings will be used when
standby.signal is present, but this is not quite the case since
recovery_target_timeline is a valid recovery target for a standby.
Update the documentation with this exception.
