I was considering also -Wtrailing-whitespace, but
1) git diff really warns just about trailing spaces/tabs, not form feeds or
vertical tabs
2) gcc source contains tons of spots with form feed in it (though,
I think pretty much always as the sole character on a line).
And not really sure how people use vertical tabs in the source if at all.
Perhaps form feed could be not warned if at end of line if it isn't the sole
character on a line...
