Subject: quote-stress-test: offer to test quoting arguments for MSYS2 sh

It is unfortunate that we need to quote arguments differently on
Windows, depending whether we build a command-line for MSYS2's `sh` or
for other Windows executables.

We already have a test helper to verify the latter, with this patch we
can also verify the former.
