I pleed guilty. I broke it in 7.9.4. :-(

Ugha. I haven't seen this one. There *is* indeed an incorrect length
calculation, but it affects the Content-Length: header libcurl issues in the
request, nothing else (that I've seen).

The content-length problem is fixed this patch:
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/curl/curl/lib/http.c.diff?r1=1.87&r2=1.88

We need to check this out.

This is my fault and you can fix this with this patch:

http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/curl/curl/lib/formdata.c.diff?r1=1.30&r2=1.31

That's my fault too. I didn't properly write what I did and didn't in regard
to my formpost changes.

Larry Fahnoe did and thanks to his tests and my patches, we made it work
again.

I'm still worried about that Expect: behavior you mention though. Can you try
some more with the above mentioned fixes applied (or possibly by getting the
7.9.5-pre1 package) and see if it still happens?
