Much better than v1 that came without any justification ;-)

I however wouldn't say "should not"---that feels a bit too strong (I
personally use "prune" from the command line once or twice every
week and do not see why I should be forbidden from doing so [*1*]),
but the users who see this message would not need such a precise
control afforded by use of "git prune", so "gc --prune=now" is a
better recommendation.

Thanks.

[Footnote]

*1* The command does not even produce a machine readable output.
    The reason it is not recommended (but that is different from
    "should not") to casual users over "git gc" is because it is a
    very focused tool (it is only about removing loose objects and
    does not touch other things) and applicable to a very specific
    condition.  Those who can recognize that they are in that
    situation should not be forbidden from using it with a dogmatic
    "should not".
