To the author: those code snippets would be 10x more readable if you got rid of the useless "admin@aws-eu-west-1-portal:compose (session 1)" preceding each input line.
Here is one write up on it: http://baymard.com/blog/line-length-readability
I think it's because I tend not to read code in order. I like to see the shape of it, look at just the beginning of the line to see what might be going on in that line and only looking at the whole line if it seems relevant to what I'm doing. Normally just seeing the first 20 or so characters (or pulling some keywords out from syntax highlighting) is enough to understand the broad strokes.
