Review Comment:
I don't like String.format() either but to me it creates garbage of quantity
comparable with String concat.
I only used it to follow the style of db qps code. I'll change it here but
reckon what we ought to do is remove the worse pattern of 'String.format()'
from the code base altogether. This way any usage will stick out like a sore
thumb.
