manifest: simplify manifest.add() by making args required

I verified that changed was never false (it was always a 2-tuple) by
adding

@@ -220,6 +225,8 @@ class manifest(revlog.revlog):

     def add(self, map, transaction, link, p1=None, p2=None,
             changed=None):
+        if not changed:
+            assert False, 'changed was %r' % changed
         # if we're using the cache, make sure it is valid and
         # parented by the same node we're diffing against
         if not (changed and p1 and (p1 in self._mancache)):

and observing that the test suite still passed. Making all the
arguments required should help future readers understand what's going
on here.

  $ hg init
  $ echo a > a
  $ hg ci -Ama
  adding a

  $ echo b > b
  $ hg branch b
  marked working directory as branch b
  (branches are permanent and global, did you want a bookmark?)
  $ hg ci -Amb
  adding b

  $ hg co -C 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

Fast-forward:

  $ hg merge b
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg ci -Ammerge

Bogus fast-forward should fail:

  $ hg merge b
  abort: merging with a working directory ancestor has no effect
