Tslint 5.13+ introduced an addition parameter for the format method, mainly used for check-style formatter.
During runtime users using an older version of tslint that doesn't expose this it is not a problem as this parameter will be ignored.
See: 9000479b69
At the moment, if a user provides multiple tsconfig, a file needs to be part of all compilations as otherwise it will fail.
This PR changes this behavour and as long as it's in one of the compilations it will not error out.
Fixes#13399
At the moment, when the tslint formatted is non human readable, it is being fully silenced.
This changes this behaviour and only emit the formatted result.
Fixes#13173
