From: Johannes Schindelin <redacted> Currently, when called with exactly two arguments, we test for a literal `..` in each of the two. However, `<commit>^!` is a perfectly valid commit range, equivalent to `<commit>^..<commit>` according to the `SPECIFYING RANGES` section of gitrevisions[7]. In preparation for allowing more sophisticated ways to specify commit ranges, let's refactor the conditional into its own function.
