 This test helps in keeping a track on which commands we can run on
 Python 3 and see what kind of errors are coming up.
 The full traceback is hidden to have a stable output.

 #if test-repo
 Make a clone so that any features in the developer's .hg/hgrc that
 might confuse Python 3 don't break this test. When we can do commit in
 Python 3, we'll stop doing this. We use e76ed1e480ef for the clone
 because it has different files than 273ce12ad8f1, so we can test both
 `files` from dirstate and `files` loaded from a specific revision.
 
   $ hg clone -r e76ed1e480ef "`dirname "$TESTDIR"`" testrepo 2>&1 | tail -1
   15 files updated, 0 files merged, 0 files removed, 0 files unresolved
 
 Test using -R, which exercises some URL code:
   $ $PYTHON3 $HGBIN -R testrepo files -r 273ce12ad8f1 | tail -1
   testrepo/tkmerge
 
 Now prove `hg files` is reading the whole manifest. We have to grep
 out some potential warnings that come from hgrc as yet.
   $ cd testrepo
   $ $PYTHON3 $HGBIN files -r 273ce12ad8f1

 Test if log-like commands work:
 
   $ $PYTHON3 $HGBIN tip

 Test bytes-ness of policy.policy with HGMODULEPOLICY
 
   $ HGMODULEPOLICY=py
   $ export HGMODULEPOLICY

 `hg init` can create empty repos
 `hg status works fine`
+`hg summary` also works!
 
   $ $PYTHON3 `which hg` init py3repo
   $ cd py3repo
   $ echo "This is the file 'iota'." > iota
   $ $PYTHON3 $HGBIN status
   ? iota
   $ $PYTHON3 $HGBIN add iota
   $ $PYTHON3 $HGBIN status
   A iota
   $ $PYTHON3 $HGBIN commit --message 'commit performed in Python 3'
   $ $PYTHON3 $HGBIN status
 
   $ mkdir A
   $ echo "This is the file 'mu'." > A/mu
   $ $PYTHON3 $HGBIN addremove
   adding A/mu
   $ $PYTHON3 $HGBIN status
   A A/mu
