[PATCH] Explicitly state that 'svnadmin hotcopy' is safe

Someone on IRC just asked whether svnadmin hotcopy is safe to run on a
live repository, because the svnadmin Subcommand Reference in the book
doesn't explicitly say so (chapter 5 does, though). This patch adds a
sentence to the subcommand reference to make it clear. The wording is
taken almost exactly from chapter 5.
