+ * keybox-file.c (_keybox_read_blob2): Return GPG_ERR_TOO_SHORT if
+ we get an EOF for 2nd to 5th byte as a better error message.
+
+ Always use gpg_error_from_syserror and gpg_err_code_from_syserror.
+ This is to avoid cases where we expect an error but due to an
+ errno set to 0 we get back a success status.

* keybox-init.c (keybox_new, keybox_release): Track used handles.
