Problems with WinSCP with end-of-line style on Ubuntu Linux when using SVN Diff

Does this thread help? More precisely this part:

From this, it seems to me that you have forced WinSCP to use text mode transfer, which imply the unix->dos conversion. Just force the binary mode to avoid the conversion.

I wasn't able to figure out why I had the whitespace issue but I was able to figure out how to ignore whitespaces.

You can use:

svn diff -x'-uw --ignore-eol-style'

This worked well enough.
