Fix trailing tabs, too.

Fix tabs that lurk around, also in empty lines, too.

Yes, we do, don't we?

fix-whitespace/FixWhitespace.hs

Lines 260 to 268 in e593b4a

	transform
	:: TabSize -- ^ Expand tab characters to so many spaces. Keep tabs if @<= 0@.
	-> Text -- ^ Text before transformation.
	-> Text -- ^ Text after transformation.
	transform tabSize =
	Text.unlines .
	removeFinalEmptyLinesExceptOne .
	map (removeTrailingWhitespace . convertTabs) .
	Text.lines

From my bare understanding of the Haskell Code, it only removes trailing tabs if tabs get converted to spaces beforehand. I ran it with --tabs=0. If it's not the case, an example file it doesn't remove tabs on empty lines & trailing tabs is: https://github.com/bionade24/Realtek-rts5229-linux-driver/blob/master/rtsx.h

Right, that likely got broken when the --tabs flag was added.
Thanks, hasn't occurred to me!
