Please use git. It has many features that svn lacks git blame -w is one
of those.

Also this change is not because these spaces are inconsistent but
because they cause problems.

When you do a diff with some spaces followed by tabs then formatting can
get weird because tab shifted. Also with trailing spaces and long line
it will wrap to new line which will look empty.

But as I looked most of lines that I changed are empty anyway so we do
not lose much of history.
