I can't check it at this moment, but I don't think any recent MS SQL (that is 7.0 and up) does this for varchars. I'm sure I would notice. It does change an empty string to a string containing the right number of spaces for char(N) columns, but there it can't do anything better. If I still remember this node tomorrow when I am at work and can try things I'll test it and post an update.
Update: Yep, I was right:
create table foo (svarchar varchar(10), schar char(10))
insert into foo (svarchar, schar) values ('', '')
insert into foo (schar) values ('')
select '>' + svarchar + '<', '>' + schar + '<'
