xonsh 0.19.3

on Python PyPI

Changed:

• On Windows, cmd.exe-based aliases now resolve to %SystemRoot%\System32\cmd.exe by default (and fallback to COMSPEC only if the former cannot be found).

Fixed:

• Using trace on with .xsh scripts could previously lead to
  a spurious ignored exception showing up on stderr. This is now fixed.
• bash_completion: Fixed empty line in completion result (xonsh/py-bash-completion#21).
• pipelines: fixed 'NoneType' object has no attribute 'pid' exception (#5794).

Security:

• The history delete action on the sqlite backend used to
  pass matched history lines to a SQL statement without sanitization.
  This could lead to unexpected SQL being run on the history database.
  This is now fixed. Security risk: low.
