You want the "::" operator to select a DAG range. From `hg help revset`:

    "x::y"
      A DAG range, meaning all changesets that are descendants of x and
      ancestors of y, including x and y themselves. If the first endpoint is
      left out, this is equivalent to "ancestors(y)", if the second is left
      out it is equivalent to "descendants(x)".

      An alternative syntax is "x..y".

    "x:y"
      All changesets with revision numbers between x and y, both inclusive.
      Either endpoint can be left out, they default to 0 and tip.

So in your case: `hg export -g -r 6828::6831`. Of course, you could also
put the SHA-1 fragments or the bookmark names in there as well. The
following is equivalent: `hg export -g -r 812891d581e1::master` (or at
least it is the same until the "master" bookmark moves).
