There was a behavior change in 1.8, where the default was changed to *not ask* until it is enabled in the config.

See http://subversion.apache.org/docs/release-notes/1.8.html#client-cert-prompt-suppression

I think the reasoning was that there are servers that allow a client certificate, but don't require one. In case you would have to use such a server but don't have a certificate you would get the question over and over again.
