'svnlook diff' fails when $TMPDIR contains symlinks

Hi,

Would someone please confirm this as a bug with svnlook in tag 1.0.2?

It's a problem for Mac OS X at least because /tmp itself is a symlink.

I searched the archives and the buglist but didn't find an existing
issue documented. Although Google found the following references to
the problem.

http://www.contactor.se/~dast/svnusers/archive-2004-04/0326.shtml

patch against 1.0.2 is attached.

log demonstrating duplication and resolution of error follow.
