Title: use system_raw in terminal, even on Windows

`system_raw` uses `os.system` instead of `utils.process.system`, and makes
more sense in a Terminal session.

There was discussion that it should be otherwise on Windows, but I can't
find any actual reason as to why this would be the case, and there are very
clear disadvantages to not using `os.system` (see #978 and #181).

If someone can actually remember the case for not using os.system, then we can ignore this, but
I can't think of a case where os.system doesn't perform at least as well.
