Aleksandar Milivojevic reported a problem in the Redhat bugzilla (see

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=134133) and not to anyone
involved in the curl project! This happens when you try to curl a file from a
proftpd site using SSL. It seems proftpd sends a somewhat unorthodox PASS
response code (232 instead of 230). I relaxed the response code check to deal
with this and similar cases.
