Extension doesn't work in Windows

[amlinux]

Extension running on Windows depends on the default terminal setting (and doesn't work in any of them).

If my terminal shell is set to bash, then the following happens:

bash: c:Usersaml.vscodeextensionsstackbuild.bazel-stack-vscode-cc-1.2.0compdbpostprocess.py: command not found

 *  The terminal process "C:\Program Files\Git\bin\bash.exe '--login', '-i', '-c', 'bazelisk build --override_repository=bazel_vscode_compdb=c:\Users\aml\.vscode\extensions\stackbuild.bazel-stack-vscode-cc-1.2.0\compdb\ --aspects=@bazel_vscode_compdb//:aspects.bzl%compilation_database_aspect --color=no --show_result=2147483647 --noshow_progress --noshow_loading_progress --output_groups=compdb_files,header_files --build_event_json_file=C:\Users\aml\AppData\Local\Temp\tmp-14324-bNEOqVPkTvzR //... && c:\Users\aml\.vscode\extensions\stackbuild.bazel-stack-vscode-cc-1.2.0\compdb\postprocess.py -b C:\Users\aml\AppData\Local\Temp\tmp-14324-bNEOqVPkTvzR && rm C:\Users\aml\AppData\Local\Temp\tmp-14324-bNEOqVPkTvzR'" terminated with exit code: 127. 

Backslashes are passed without escaping to bash.

If I set it to Powershell, then the command is not modified and still uses bash-specific &&:
