Windows: Multiple arguments unsupported

[robertschweizer]

Single-argument commands work, e.g.

from subprocess_tee import run
run(["git"])

With multiple arguments, an error is raised:

$ python -c "from subprocess_tee import run; run(['git status'])"

FileNotFoundError: [WinError 3] The system cannot find the path specified

The reason is probably that platform_settings["executable"] is set on Windows: https://github.com/pycontribs/subprocess-tee/blob/v0.4.1/src/subprocess_tee/init.py#L57-L58

Workaround

Pass executable=None:

from subprocess_tee import run
run(["git", "status"], executable=None)
