True enough.  I personally do not mind any of the three variants
(including the original) and would rather not spend too much time
micro-optimizing this codepath, lest the next clever person starts
to turn the loop in for_each_loose_file_in_objdir() to a nested loop
that runs 16 times each to avoid copying the same leading byte again
and again ;-)
