URLs containing such codes could easily otherwise be used to do harm and allow users to do unintended actions with otherwise innocent tools and applications. Like for example using a URL like pop3://pop3.example.com/1%0d%0aDELE%201 when the app wants a URL to get a mail and instead this would delete one.

In 0.9.6e they added a bit to SSL_OP_ALL that _disables_ that work-around despite the fact that SSL_OP_ALL is documented to do "rather harmless" workarounds. The libcurl code uses the SSL_OP_ALL define and thus logically always disables the OpenSSL fix. In order to keep the secure work-around workding, the SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS bit must not be set and this change makes sure of this.
