Subject: SSL: Handle EOF case in ssl_get
X-Git-Tag: v4.2.8~6
X-Git-Url: http://git.indexdata.com/?p=yaz-moved-to-github.git;a=commitdiff_plain;h=ec603701ef51f85beef83898aa36e385028692f1

SSL: Handle EOF case in ssl_get

If gnutls was in use and gnutls_record_recv returned 0 (EOF)
the ssl_get function would never terminate.
