Automatically add newline at end of curl response body

From the man file:

To better allow script programmers to get to know about the progress of
curl, the -w/–write-out option was introduced. Using this, you can specify
what information from the previous transfer you want to extract.

To display the amount of bytes downloaded together with some text and an
ending newline:

curl -w 'We downloaded %{size_download} bytes\n' www.download.com

So try adding the following to your ~/.curlrc file:

-w "\n"
