A semicolon should be used without a conjunction, and the parts of a sentence joined by a semicolon should be independent clauses. So this should probably be

                                                     [...] The value
    "now" may be used to disable this grace period and always prune
    unreachable objects immediately, or "never" may be used to
    suppress pruning.

The same here.

Similarly, this could be fixed to

                               [...] The value "all" expires all
    entries; "false" disables expiration. [...]

The same here.

Also, I wonder why you suggest "now"/"never" for the first two settings, but "all"/"false" for the second two. Wouldn't it be less confusing to be consistent?
