I do RTM!

It's not that I don't RTM. It's just that my skimming sucks!

After I couldn't find this in "man curl", I found this explanation. Then I was able to find "--data @foobar" in the man page.

~/$ history|grep 'man curl'
645 man curl
1325 man curl
1327 man curl
1446 man curl
1456 man curl
1467 man curl
1472 man curl
1509 man curl
1663 man curl
