 `-ghci-script` are executed in reverse order and are ignored when
 `-ignore-dot-ghci` is specified, while I expected that:
 * `-ghci-script` are executed in the order they are specified;
 * `-ignore-dot-ghci` only ignores the default .ghci files but still
 executes the scripts passed by `-ghci-script`.

 I would like to change the behavior to the expected ones. But in case
 there are users relying on the old behavior, then it might be necessary to
 introduce different flags.
