But what is the "revision of the file"?  The blob ID is just a hash of
the contents, and doesn't say anything about where in the history of
the project it appears.  It will usually appear in many "project
revisions", i.e. commits.

If you want to mark the "revision" of a file, the only sensible thing
is to use the commit ID, which will give you all the problems
described in this thread.
