Relatedly, some future topics I'd like to have at some point and that would require the same kind of hooking: - committish mapping resolution. It's not really clear what I mean with this, but here's the idea: You're using a remote helper to talk to a non-git repository. Common examples are svn, p4 and mercurial. I'm not sure how this would work for svn, or what p4 revisions look like, but speaking as someone who clones mercurial repositories with git (and working on one of the tools to do so), there are many cases where I wish I could just do something like: git show hg::d4a5c8fbfc20cebcae60d1e073874d19fa47d831 where d4a5c8fbfc20cebcae60d1e073874d19fa47d831 is a mercurial changeset id. And this is a simple example, but the idea is that it would work anywhere we can use committishs and revranges. Ideally, it would also work with abbreviated mercurial changesets e.g. hg::d4a5c8fbfc20 - providing information for --decorate Here the idea would be the converse of the above, and would make e.g. `git log --decorate` show hg::d4a5c8fbfc20cebcae60d1e073874d19fa47d831 or the abbreviated form hg::d4a5c8fbfc20 for the corresponding git commit.
