-projecthelp is the same as asking Ant to run a target that doesn't
exist here (at least to me).  In both cases I don't expect any
persistent side effects to happen, which could probably only be done
by not executing any tasks at all.

That's what I tried to say. 8-)

But nowadays, almost every task can set a property (<exec> can, for
example).  So maybe it shouldn't be as broad.

Yes, I know that - and users have asked for it of course.  But things
are a bit different in Ant (only talking about make's -n) as the
logging you get from tasks like <javac> if you don't perform a
directory scan is rather useless.

But I agree that the whole issue of which task should run under what
condition is closely related to -dryrun and may get resolved at the
same time.
