The git extension is bundled in-tree, similarly to the hg gui, but also requires pygit2. Enable it for mercurialFull, but don't bother with it for the stock mercurial install. Alas, it doesn't (yet?) work on nixpkgs because it doesn't support octopus merges: mercurial.error.ProgrammingError: git support can't handle octopus merges, found a commit with 16 parents :( I'm sure that commit is loved equally by all 16 parents.
