See this thread. The first line of my response is code and I did not forget to indent. I also used the </> Code button. It turned green like it should, so it looked fine. Then I hit submit and the code was in regular text. Edited it a few times, each time looked right, but posted wrong. Using Chrome on Windows 10.

We trim leading and trailing whitespace that is submitted by forms. Since it's not intuitive, I'll correct this behavior.

Should be corrected now.
