I forgot to say why.  Although this might result in generated code that
does unnecessary work, on the other hand it might not.  Concern for such
low-level "microefficiency" is nearly always misplaced.  If this
particular test occurred in bottleneck code, then it might be worthwhile
to tweak it, but in the vast majority of cases the visually simpler code
is preferable.
