The svn relocate subcommmand reference example, following the paragraph beginning with "Let's look at one final relocation opportunity", shows an http URL instead of https. This example for switching to SSL-only access should read:
$ svn relocate https://svn.company.com/repos/trunk
$
Fixed in revision r5041.
Backported the fix to the 1.7 version, too (r5042). Thanks, Jose!
