Yes.  Renaming it as something else would probably be silly; I was being (at
least) temporarily stupid.

It's probably cleaner, and is arguably more correct, than the effect level
patch.  It could be extended, by analogy, to the chorus effect module by adding
a fluid_clip() operation there, and probably adjusting the initial level.  

Another point is whether the following element of the effect level patch should
be kept or removed (in fluid_chorus.c:fluid_chorus_processreplace):

    /* average values based on number of chorus stages */
    if (chorus->number_blocks)
      d_out /= chorus->number_blocks;
