Suggestion: cquery cannot parse `includePath` with space

[magic3007]

Platform: win10 editor: vscode

Environment variables are listed below:

> set MSMPI
MSMPI_BENCHMARKS=C:\Program Files\Microsoft MPI\Benchmarks\
MSMPI_BIN=C:\Program Files\Microsoft MPI\Bin\
MSMPI_INC=C:\Program Files (x86)\Microsoft SDKs\MPI\Include\
MSMPI_LIB32=C:\Program Files (x86)\Microsoft SDKs\MPI\Lib\x86\
MSMPI_LIB64=C:\Program Files (x86)\Microsoft SDKs\MPI\Lib\x64\

And the c_cpp_properties.json is

{
    "configurations": [
        {
            "name": "Win32",
            "includePath": [
                "${workspaceFolder}/**",
                "${env:MSMPI_BIN}",
                "${env:MSMPI_INC}",
                "${env:MSMPI_LIB32}"
            ],
            "defines": [
                "_DEBUG",
                "UNICODE",
                "_UNICODE"
            ],
            "windowsSdkVersion": "10.0.17763.0",
            "compilerPath": "C:/Program Files (x86)/Microsoft Visual Studio/2017/Community/VC/Tools/MSVC/14.16.27023/bin/Hostx64/x64/cl.exe",
            "cStandard": "c11",
            "cppStandard": "c++17",
            "intelliSenseMode": "msvc-x64"
        }
    ],
    "version": 4
}

However, cpptools can pharse the environment variables ${env:MSMPI_BIN}, ${env:MSMPI_INC} and ${env:MSMPI_LIB32}, but cquery cannot.

The reason is that these environment variables have space within them, which is frequently occurred in Windows. I hope it could be fixed.
