I think this could make clear that the first paragraph talks about
`--ff`. I know that we often list `--foo` and `--no-foo`, say "This
option does bar" and leave it to the reader to figure out which is which.
Most of the time, that's fairly obvious though (foo=bar). With this
tri-state option, we might be past the point of fair obviousness.
Then again, seeing "ff" and "fast forward", it's not /that hard/ to
figure out.

Apart from that, this reads well. Of course with the usual caveat of
the topic being fresh on my mind, so in general, I'd be more likely to
understand what it is I'm reading. ;-)
