Looks like you've got it figured out ... but just in case, here are my
settings:

httpd.confg, In my location section for my SVN store:

SetOutputFilter DEFLATE
SetInputFilter DEFLATE
BrowserMatch ^Mozilla/4 gzip-only-text/html
BrowserMatch ^Mozilla/4\.0[678] no-gzip
BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png|msi|exe|pdf)\$ no-gzip
dont-vary

In my modules section in httpd.conf:

and in my local subversion\servers file:
[groups]
group1 = mysvnserverdomain.com <http://mysvnserverdomain.com>

### Information for the first group:
[group1]
http-compression = yes

You have to turn in the input filter as well to get the (server) inbound
compression.

hth,
Kyle
