You can only ignore whitespaces in a diff. But you can't ignore them
when updating or merging. After all, you want your working copy to
reflect the state of your repository, otherwise you couldn't commit.
You should set the svn:eol-style property on your files to avoid such
problems.

The whitespaces of 'theirs', but from 'mine' if 'mine' has lines which
'theirs' doesn't.

Of course: how should Subversion/TSVN know that you don't care about
whether a space is there or a tab? There are programming languages where
that makes a *big* difference. So Subversion *has* to treat those
differences as real differences and can't just ignore those.
It *can* ignore those for *showing* you a diff, but that's all.
