posting data with first url only

From: Peter C. McCluskey <pcm_at_rahul.net>

 I'm submitting patches to add an option to have -d data applied only
to the first url, and to use GET for subsequent urls. I seemed to need
this to handle a site which has a nonstandard login requirement.

 If this option is used several times, the ones following the first will
 append data.

+.IP "--data-once"
+(HTTP) This causes all data specified by \fI-d/--data\fP or \fI--data-binary\fP
+to be sent only with the first URL, and causes curl to use GET for subsequent
+URLs. It can be useful for handling login forms.
