serving canopy blogs from a local git repository #67

I would like to test a local git repository for Canopy blog posts before pushing it to the actual repo. I built Canopy locally, but then I have not manage to get it to read posts from a local git repository.

Could this be supported? I grepped for not a supported protocol in the sources but couldn't find any hit for this error message. Which piece of the ecosystem is it that fails to support file?

Also, why does Canopy still run a server and loops infinitely when it failed to resolve the Git repository? Is there anything useful in that, or could it just not quit on this error?

Canopy should quit if it fails to load its remote git repository.

I suspect the code responsible for resolution of protocol to how to communicate there is likely hidden somewhere in git or in conduit, but I'm not able to spot it right now... @samoht might be able to quickly point out where the code is
