Close FILE pointer in anno for -append as well as -delete.

https://savannah.nongnu.org/bugs/?23465 has Peter Maydell pointing out
the assymetric open and close of a FILE pointer.  He's right on that
AFAICS so change the test to be for a non-NULL pointer rather than the
more wordy and prone to error flag-testing.
