Subject: git-blamer: Run `git show` on <Enter>

When the `<Enter>` key is pressed in the GitBlamer window, run
`!git show` on the commit from the current cursor line of the blame.

This allows a changed line to be inspected in the context of its
original changeset. It also saves me time from my previous workflow:

    cpe^Zgit show <Apple-P><Enter>
