Terminal input length restricted under Windows 7.

[ericsnowcurrently]

• VSCode Version: 1.30.2
• OS Version: Windows 7

When using the Python extension under Windows 7, running "Run Selection/Line in Python Terminal" truncates long lines sent to the terminal. This was reported by a user of the extension in microsoft/vscode-python#4122 (which contains more detailed information).

More details:

• problematic line was 1589 characters (truncated to 1467)
• behavior happens under both cmd & powershell
• not truncated if pasted info cmd or powershell directly
• not truncated under Windows 10

While WIndows 7 is soon to EOL, understanding the root cause may still be useful.
