trailing whitespaces?

[mmaker]

Hi, I just wanted to report that there are around 2KB of trailing whitespaces, which are superfluous and could be confusing for patches.

$ du --bytes --exclude .git
104146	./ref
60495	./avx2/keccak4x
243768	./avx2
20410	./scripts
374081	.
$ find . -type f -not -path './.git/*' -exec sed -i -e's/[[:space:]]*$//' {} +
$ du --bytes --exclude .git
103351	./ref
60495	./avx2/keccak4x
243270	./avx2
20209	./scripts
372585	.

This is a list of affected files:

$ git status

no changes added to commit (use "git add" and/or "git commit -a")

Perhaps you want to configure your editor to strip them automatically?
Good luck !

(I didn't submit a patch because well… I guess it's a mess to check. But the find kung-fu up there should do the job, and it's easier to review :) )
