 To exclude commits reachable from a commit, a prefix '{caret}'
 notation is used.  E.g. '{caret}r1 r2' means commits reachable
-from 'r2' but exclude the ones reachable from 'r1'.
+from 'r2' but exclude 'r1' and those reachable from 'r1'.

Well, if you have to spell that out, you'd want to spell out r2 side
too, no?  That is,

The clarification wasn't about what "reachable" means but about inclusivity,
such as whether 0..4 would give 0,1,2,3,4 or would be 'off by one' and only
give 1,2,3,4. And in this case it's the latter.

Well, you have the same inclusivity issue on the opposite end, no? Is 0..4
a range with 0,1,2,3,4? 0,1,2,3? 1,2,3,4? or 1,2,3?

Describing 'reachability' is a whole different kettle of fish, as you
highlight below, and would be separate from this patch.

I am not sure I agree. It all is about "is the endpoint included or not?".
