Document that File::Find doesn't follow symlinks

Subject: following symlinks with File::Find

The behaviour of File::Find with respect to symbolic links is inconsistent
between Perl 5.002/5.003 and 5.004_02.  Since 5.004_02's behaviour (don't
follow symlinks) is more consistent with `find' itself, this is probably
more of a documentation bug -- i.e., the File::Find man page should
mention that 1) it doesn't follow symlinks, and 2) previous versions
did, so watch out!
