  * implement hunkMatches for PatchInfoAnd
  There doesn't seem any reason not to have it and it allows
  simplifying other code.

* break RebaseItem out into its own file
  
moves Item-related code to Darcs.Patch.Rebase.Item , and one name-related
function to Darcs.Patch.Rebase.Name (from Darcs.Patch.Rebase).

* move Rebasing out into its own module

Introduces Darcs.Patch.Rebase.Container, which handles the patch that
represents the rebased state. Moves code from Darcs.Patch.Rebase to this
new module.

* implement hunkMatches for PatchInfoAnd

ok; previous code was strangely incomplete indeed.

* simplify the PatchInspect (Rebasing p) instance

It does so by introducing a PatchInspect (RebaseItem p) instance. OK.

* drop unneeded export

OK.


Accepted.
