Hmmm, this means that your local Git server is unhappy with the size of
the request.  That means your request is probably very large, and it's
likely that it is kindly asking you not to DoS it.

You may want to try this:

  xargs git fetch origin < .git/missing.list

That will batch the requests to fit on the command line, which will
probably also have the pleasant side effect that it makes each
individual request smaller to avoid the 413.
