Environment variables in hook scripts?

Hello,

In the official Apache Subversion FAQ I see the entry:
http://subversion.apache.org/faq.html#hook-debugging.

The entry says:

[[
Before Subversion calls a hook script, it removes all variables --
including $PATH on Unix, and %PATH% on Windows -- from the
environment. Therefore, your script can only run another program if
you spell out that program's absolute name.
]]

Is this statement true?

I've just tested this with Windows 7 64bit and Apache Subversion
1.7.8: NO environment variables get removed.

Am I doing something wrong? Is the FAQ entry obsolete?
