Fixed a problem when --dump-header - was given with more than one URL,

which caused an error when the second header was dumped due to stdout
being closed.  Added test case 1066 to verify.  Also fixed a potential
problem where a closed file descriptor might be used for an upload
when more than one URL is given.
