-Create a repo such that the changelog entry refers to a null manifest node:
+Test null revisions (node 0000000000000000000000000000000000000000, aka rev -1)
+in various circumstances.
+
+Make an empty repo:
 
   $ hg init a
   $ cd a
-  $ hg log
-  $ touch x
-  $ hg add x
-  $ hg commit -m "init"
-  $ hg rm x
-  $ hg commit -q --amend
 
-  $ wc -c < .hg/store/00manifest.i
-  0
-
-Make sure that the manifest can be read (and is empty):
-
-  $ hg --config rhg.on-unsupported=abort files -r .
+  $ hg files -r 0000000000000000000000000000000000000000
+  [1]
+  $ hg files -r .

-Test a null changelog rev, too:
+Add an empty commit (this makes the changelog refer to a null manifest node):
+
+
+  $ hg commit -m "init" --config ui.allowemptycommit=true
 
-  $ hg --config rhg.on-unsupported=abort files -r 0000000000000000000000000000000000000000
+  $ hg files -r .
   [1]
+
+Strip that empty commit (this makes the changelog file empty, as opposed to missing):
+
+  $ hg --config 'extensions.strip=' strip . > /dev/null
+
+  $ hg files -r .
