[PATCH v6 18/21] completion: support `git range-diff`

From: Johannes Schindelin <redacted>

Tab completion of `git range-diff` is very convenient, especially
given that the revision arguments to specify the commit ranges to
compare are typically more complex than, say, what is normally passed
to `git log`.
