In some circumstances (like running guilt in a M-x shell buffer in
Emacs) cat may give the above error message when the reader of the
output from cat exits without reading all input from cat. (In other
circumstances cat is just silently terminated with SIGPIPE.)
Get rid of the error by removing the useless use of cat in
do_get_header and do_get_full_header.
