Description Robin Stocker

It would be nice if we could provide the commits that are selected in the history view to external tools, so that e.g. a launcher for "git difftool" could be created.

Currently, we offer these variables: git_branch, git_dir, git_repo_relative_path, git_work_tree.

We could add something like git_commit_1 and git_commit_2, or if there is support for an array of values, just git_commit[N] (don't know the syntax).

Should not be too hard to implement, patches welcome!

See the following question on Stackoverflow for the idea:
