CURLOPT_URL docs: no need to mention function names

The path part of a SMTP request specifies the host name to present during

communication with the mail server. If the path is omitted then libcurl will

perform a call to \fCurl_gethostname\fP to resolve the local computer's

host name. However, \fCurl_gethostname\fP does not return the fully qualified

domain name that is required by some mail servers and specifing this path

allows you to specify an alternative nane such as your machine's fully

qualified domain name which you might have obtained from an external function

such as gethostname or getaddrinfo.
