    Thanks.  I installed the patch below which fixes the problem at least on
    this trivial file.  And sorry for taking so long.  Please confirm that
    it fixes the problem in real life as well.

Thanks. I rebuilt Emacs from trunk r114733 to test. `vc-annotate' no longer signals an error, but neither does it work correctly. For non-trivial master files, many lines are wrongly attributed to revision 1.1.
