I've tried this. But in this case curl will stop transfer not after 2048
bytes will be received, but when pipe will be closed and it can't write
there next part of data. For example when i use --max-hard-filesize,
curl gets 2353 bytes, using head - 4111.

home% ./curl --max-hard-filesize 2048
"http://www.google.com/search?q=something" > /dev/null
