Summary: nedit doesn't fsync/fdatasync when saving

Initial Comment:
nedit, when the user instructs it to save, should perform a fdatasync or fsync on the file descriptor immediately after the write calls. Firstly, because POSIX gives no guarantee of when the file will reach disk otherwise. Secondly, because some errors during writeback can only be caught then. For example, AFS defers all writes until the file is fsynced or closed. Checking the error code from fsync/fdatasync is the only way to detect resulting errors.

I believe nedit isn't doing either fsync or fdatasync, because strace doesn't show them being made.
