I'm not clear why you can't just run something like tr '\012' '\040' to
replace all newlines with spaces, so that you pass one long, long line
to curl. On most server platforms there is no meaningful "line length"
limit to a URI (that is, there is a limit but it's in the thousands or
tens of thousands of bytes).
