This option string is parsed by HTTPD.
The API provided by HTTPD is quite bad for this use case.

This is work in progress, and the above behaviour will be changed.
See http://subversion.tigris.org/issues/show_bug.cgi?id=4113

In the long term, the argument to the SVNHooksEnv option will be changed
anyway. It will become a path to a file which contains a list of environment
variables and their values. That file will then be parsed by our own config
parsing code.
