Minor upgrade issue

[Steven Shockley]

When following https://www.openbsd.org/faq/upgrade69.html, I noticed a 
minor error when deleting the Perl files:

<root@cvs:/root:1>: rm -f /usr/bin/podselect \
>           /usr/lib/libperl.so.20.0 \
[...]
>           /usr/share/man/man3p/Pod::Select.3p
rm: /usr/libdata/perl5/amd64-openbsd/Tie: is a directory
rm: /usr/libdata/perl5/amd64-openbsd/auto/Tie: is a directory
Maybe it should be rm -rf?  Or I missed a step.  Of course I could just 
use sysclean.  Thanks.
