Re: [PATCH 0/3] Fix assorted white space damage

Following there is a 3  patch series to remove stealth whitespace.

I have used the new 'cleanfile' script by H. Peter Anvin, just merged
in Linux tree.

The script cleans up various classes of stealth whitespace.  In
particular, it cleans up:

 - Whitespace (spaces or tabs)before newline;
 - DOS line endings (CR before LF);
 - Space before tab (spaces are deleted or converted to tabs);
 - Empty lines at end of file.

I haven't checked the script, but "git-apply --whitespace=strip"
can be used to do pretty much the same job with this sequence,
except the last one (do it with a copy of repository if you do
not want "git clean -x" to lose untracked):


	$ git checkout master
        $ rm -f .git/index
        $ git checkout HEAD -- t/
        $ git clean -x -d
	$ git diff -R --binary HEAD >P.diff
        $ git apply --index --whitespace=strip P.diff

Then you can check the results, and make a commit.

In the above I explicitly "saved" t/ because we have some test
vectors that need to have trailing whitespaces.
