OK, this should not happen.

The correctness of this conversion was not immediately obvious, as
"git rev-parse --parse-options" could allow end-users to specify
flags, and when these two flags came together from that codepath, it
is an end-user error that should be diagnosed with die(), not BUG().
It turns out that stop-at-non-option can be passed, but keep-unknown
is not (yet) available to the codepath, so this conversion to BUG()
is correct---an end user futzing with Git correctly compiled from a
bug-free source should not be able to trigger this.
