Kurtis Rader 7d65141137 be quiet when make style does nothing
The `make style` and `make style-all` commands have been performing well
without glitches for long enough that it is no longer necessary to report
when they don't change the style of a file. Especially in light of the
fact that all the relevant code has been restyled in the past year. This
change makes `make style-all` much less noisy.
