Yay, it will be great to get more people doing this!

@jimhester 🙂 Explanation not for you, but to document for others.

How did I achieve this? I executed the code below and pasted into this issue. What's important?

• venue is GitHub (venue = "gh"), which is the default
• si = TRUE

That appends session info AND folds it nicely into a Details tag.

input <- c(
  "#' Hello world",
  "## a comment",
  "(x <- 1:4)",
  "#' hi again",
  "y <- 2:5",
  "x + y"
)
output <- reprex(input = input, si = TRUE)

What's not important? This specific use of input. This should work with any method of providing reprex source (clipboard, expression, character, file path).
