But you could apply the patch to your working copy.

Does that really correspond to the previous behavior?

    ...
    (when (eq 0 status)
      (if (string-match "changeset: *\\([0-9]*\\)" out)
          (match-string 1 out)
        "0"))))

It returns "0" when there is no match but nil if status doesn't equal 0:

  when is a Lisp macro in `subr.el'.
  (when COND BODY...)

  If COND yields non-nil, do BODY, else return nil.

Also, iget a quoted string, e.g. "\"290\"", which is why I used read.
