I think what the patch does makes sense.  When svn:special
exists, check if it is of form "link " and munge the way a
symlink is represented to match what we expect.  

My understanding is that currently there is any type of special
svn blob defined other than "link ", and dying rather than
punting and silently doing a wrong thing when we see something
else in the future makes sense to me as well.

Previously we were feeding "update-index --cacheinfo" with
'0755' and '0644', but this patch changes it to send
100755/100644; technically this is not necessary, because
create_ce_mode(m) makes it a regular file unless S_ISLNK(m), but
I think this is good for consistency.

Karl, Martin, Smurf, Comments?
