The unit tests only assert the arguments lazygit constructs; they can't
catch cmd.exe's own quote-stripping, which is where #5560 actually
manifested. This test builds a small editor executable, places it and
the file it opens at paths containing spaces, runs it through real
cmd.exe via NewShell, and checks the editor received the intended args.
It runs only on Windows.
