There's nothing new here; it's all just rebased on top of the updated safe branch. In order, we have

  * David's patches that remove the "top" and "bottom" patch fields.
    These need a format version upgrade function (trivial), but are
    otherwise ready, I think.

  * David's conflict refactoring series, with some fixes by me, and
    removal of some commands that become superfluous. Almost ready,
    but it makes ugly conflict markers, and "stg resolved" should
    probably be removed.

The following changes since commit 2299c463794f214b750ecc33e24779243ddc5aff:
  Karl Hasselström (1):
        Make "stg refresh" subdirectory safe

      Remove the 'bottom' field
      Remove the 'top' field

Karl Hasselström (9):
      Better error message if merge fails
      Fix "stg resolved" to work with new conflict representation
      Refactoring: pass more than one file to resolved()
      We keep the different stages of a conflict in the index now
      Clean up the logic in "stg resolved"
