Not able to use run magic with file path contain -m in windows

[dddping]

strange error message

• To run magic
  %run "r:\abc\abc.py"
  If file not exist, the error msg should be File 'r:\\abc\\abc.py' not found.
• However, sometimes it mess up the path...
  For example
  %run "r:\abc-m\abc.py"
  Error msg File '\'"r:\\abc-m\\abc.py"\'.py' not found.

Insight

The function para parameter_s seem to get mess up by following branch
if '-m' in parameter_s and '--' not in parameter_s:
Let say parameter_s = "r:\abc-m\abc.py", but since it contain "-m" in the path, it will change to "'r:\abc-m\abc.py'" after above if clause.
