Description

The value of args should quote comspec. Otherwise the shell process won't parse its command line correctly if comspec contains spaces.

Research direction

The issue names subprocess argument construction and the comspec value, but no file or test. Start by tracing where the subprocess args string is formed and inspect Windows-specific subprocess coverage. Done means comspec paths containing spaces are quoted so the shell parses the command line correctly.
