Not a bug.  POSIX allows this behavior, and Linux does it as well.  POSIX
also allows BSD behavior of seeking to the end, although this is less
friendly to reading back a file opened with fopen(...,"a+").  So portable
programs can't expect either situation, and you MUST use fseek when
opening for append if you expect a particular position.
