  Log Message:
  -----------
  Do not make assertions about stdlib's doctest.py

The source code in stdlib's doctest.py changed between Python 3.7 and
3.8 sufficiently to break even the cut down assertion we already have.

      {red}      File ".../lib/python3.8/doctest.py", Line NNN, in __run{normal}
    - {red}        compileflags, 1)...{normal}
    + {red}        exec(compile(example.source, filename, "single",{normal}

I get the feeling Python 3.8 points to the first line in a multiline
statement in tracebacks, whereas older Python versions usually pointed
to the last line.

  Fix test failure on Python 3.8

As I mentioned in the previous commit, Python 3.8 prints the first line
of a multiline statement instead of the last line:

      TypeError: Invalid test_suite, None, in tests2
      > ...find.py(NNN)find_suites()
    - -> % (suite, module_name)
    + -> raise TypeError(
      (Pdb) c
      EndRun raised

We don't need to care about that if we convert this to a single-line
statement.

  Avoid PowerShell in Appveyor

PowerShell treats any output to standard error (such as pip's
deprecation warning about Python 2.7 and 3.4 reaching EOL soon) as a
fatal error.
