[Windows] Unresolved reference on links to files that are in folders

[rutgersc]

See for example the following:

// nested/testlink.md
stuff

// linktester.md (windows) 
[[testlink]]: Unresolved Reference
[[nested\testlink]]: Works
[[nested/testlink]]: Unresolved Reference

// linktester.md (mac) 
[[testlink]]: Works
[[nested\testlink]]: Unresolved Reference
[[nested/testlink]]: Works

I would expect [[testlink]] to work on windows but it currently seems broken. Likely some issue with slashes?

Yea it is likely due to rust path library.

This will be fixed in v1; We will chose /, not windows path.
