+Any extra arguments you might want to hand to curl(1). The arguments
+should be separated by the regexp specified in "extrare", which
+contains just the space character (" ") by default.
+
+Note that curl will be called with the resulting list of arguments
+without any shell expansion. If you need to specify any arguments
+containing spaces, you should set "extrare" to something else.
+
+As a complicated example, to explicitly set the "Host:" header in Curl
+requests, you need to set "extrare" to something else, eg. "/;/",
+and then specify C<extraargs = --header;Host: www.example.com>.
