Question about IPLD Git URLs

[billiegoose]

Hi! Lead author of isomorphic-git here. In preparation for Chrome whitelisting of ipfs and git schemas in registerProtocolHandler (Firefox already has I believe) I'm investigating how git URLs handle paths to trees and blobs. AFAICT git uses URLs to identify repos but doesn't specify a standard URL format for identifying branches and blobs inside repos. npm uses a # sign after the repo url to identify a branch or SHA1. How are you handling this in IPFS? What's a fully qualified git IPLD reference to a blob look like? If git doesn't have a native way to do it, I'd rather be compatible with IPLD than make up a convention.

Secondly, the parsers and serializers look similar to the ones I wrote for isomorphic-git; we should compare notes sometime! Maybe we can consolidate the parsers and serializers into standalone modules that others can use?
