Error: open output/dir\foo.txt: The system cannot find the path specified.

Only last path separator is \ (backslash), not / (slash). Might be related.

Panic Output

Expected Behavior

It should generate files in subdirectories as well.

Actual Behavior

No files generated and terraform stops with an error. Only occurs on windows. When running terraform from docker, it successfully generate files.

Steps to Reproduce

On powershell,

1. mkdir input\manifests
2. echo foo > input\manifests\foo.txt
3. terraform apply

Important Factoids

I updated an example with minimal one.
