vim:keys: Reference commits w/ --pretty=reference

Use git's preferred way of referencing commits (`--pretty=reference`)
instead of the kernel's (`--pretty='%h ("%s")'`). I can see that
specifying the date makes sense and that the quotes are at best
unnecessary in the parentheses and at worst confusing when the subject
contains quotes itself.
