On Windows this is not the entire story: If you didn't explicitly accept the
certificate in Subversion (or via a custom openssl config), but
automatically accept it via the Windows Crypto API and its certificate
store, then CRLs are used... 

So you would see Subversion prompt for an untrusted certificate in case the
certificate is revoked.
