tests: fix readline escape characters in heredoctest.py/test-url.py

This fix mirrors the changes made to test-doctest.py in b856071435f7
and 967adcf5910d.

Without this change, tests running heredoctest.py can fail on certain
versions of OS X when TERM is set to xterm-256color:

   $ /opt/local/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python -m heredoctest <<EOF
   > >>> open('b', 'w').write('this' * 1000)
   > EOF
+  \x1b[?1034h (no-eol) (esc)

A similar problem occurs with test-url.py:

  $ ./run-tests.py test-url.py

  --- .../tests/test-url.py.out
