I often have to rewrite questions/answers that I or other people have written because they are reformatted between being typed and them being posted on the site. I shall use "I" to mean "I or someone" from now on.
For example I write:
test1: 22ms test2: 23ms test3: 24ms
When I typed this I put return characters at the end of each line, so each test is on its own line. But Stack Exchange takes out these return characters squeezing my test results into a single horrible line, why?
As stated within the Markdown editing help you can get true new lines by adding two spaces after the line:
My point isn't so much that you can't work around these issues but that Stack Exchange is creating poorly formatted questions by taking mildly badly formatted questions and converting them to very poorly formatted questions. Is this behaviour of not honouring single return characters beneficial elsewhere? Is there some advanced formatting that relies upon it?
Whitespace is one of the best ways to improve clarity.
