doc/articles/wiki: move _ warning slightly higher at one point #22617
Description
Currently working myself through https://golang.org/doc/articles/wiki/ and got stuck at the first HTTP server example. It doesn't have any error handling but easily runs into a bad Go panic
2017/11/07 20:08:24 http: panic serving 127.0.0.1:48718: runtime error: invalid memory address or nil pointer dereference
Took me some time to find out that I was missing the test.txt file. Created a solution comment before noticing that pull requests to are not allowed but don't want to go through the full contributor process right now just to add few lines to the tutorial page.
You may copy from my commit or write something else, but there should be a hint for others running into the same problem:
