Ah, yes, that function should indeed get used for each instance of SSL
object initialization, so the changes to the context values would
probably not have been needed (not that they do any harm). This per-SSL
object code is from 2004, but I'm not sure why exactly that was added
initially since TLSv1_method() was used then. Anyway, this is just an
unnecessary, duplicated disabling of the old protocol versions.
