Diff between commits

[calvn]

First and foremost, this it an awesome package, just what I was looking for! I came across this and spent some time reading the docs, but couldn't find reference to how git-diff can be done, similar to https://godoc.org/github.com/libgit2/git2go#Diff. I noticed that there's https://godoc.org/gopkg.in/src-d/go-git.v3/diff, but this is more for comparison of the contents between a src and dst, which is different from retrieving a list of the diff files between two commits. Is functionality not available in go-git, or did I miss it in the docs?

The Diff entity is the bare part of the diff, but currently we don't provide a direct method from a commit for retrieve the diff from the previous file or tree. Sorry

@mcuadros @ajnavarro I was actually trying to use this and it is able to create a patch, but for my use-case, I need to create a format the patch with extra lines in the context which we are able to achieve via format-patch option on git cli

       -U<n>, --unified=<n>
           Generate diffs with <n> lines of context instead of the usual three. Implies --patch.

Is there any similar option available in the library?
