xonsh 0.6.8

on Python PyPI

Fixed:

• completions relative to CDPATH only trigger when used with cd
• Import of ctypes.util is now explictly performed, as needed.
  Python v3.7 no longer imports this module along with ctypes.
• Fixed issue with pygments-cache not properly generating a cache the first
  time when using prompt-toolkit. This was due to a lingering lazy import
  of pkg_resources that has been removed.
• Removed duplicate pip completer
• bash_completion no longer returns invalid prefix lengths for directories
  containing escape file names
• Fixed error when using redirection (e.g., >) on Windows.
