All ssl properties are read from the subversion config file "servers".
So subversion seems to evaluate them.
Also the subversion command line client evaluates the no-promt option.
Basically my proposal says that "servers" should get a default value for
"no-promt".
Because of this, although not being a professional developer, I am quite
sure
that it would be easy possible in subversion.

This is ssh. Is there a corresponding ssl option? This would be perfect!

Thanks!
