Ah ok, yes I agree that your version of the if statement will produce
the desired behaviour (as long as servercert() also checks the values of
"ssl.verifypeer" and "ssl.verifyhost" before it actually performs the
validation and sets the return code).

 

I've not used git before but can I take it from the fact that you've
done a diff here that this is something that's already been fixed?
