Ensure all source-code displays without horizontal scrolling

[jlperla]

For example, in http://compare-lectures.quantecon.org/jl/julia_by_example.html#

To do this, we will need to shorten the lines of code.

• If it is actual code then we can use string concatenation, i.e. instead of

  println("Fixed point = $(sol.zero), and |f(x) - x| = $(norm(f(sol.zero) - sol.zero)) in $(sol.iterations) iterations")

  maybe something like (noting the use of * as string concatenation to make it multiple line correctly

  println("Fixed point = $(sol.zero), and |f(x) - x| = $(norm(f(sol.zero) - sol.zero))"*
  "in $(sol.iterations) iterations")

• If it is due to comments on the right of equations being too long we can move the comments to their own line before the equation. Or we can remove/shorten the comments if they don't seem to make much sense. For these, don't forget the style guide https://github.com/QuantEcon/lecture-source-jl/blob/master/style.md#naming-conventions-comments-etc

@Nosferican @arnavs It might be helpful to figure out the length at which scrolling appears, if you have any ideas? We could then could check that column width in our editors.

Scrolling kicks in at 99/100 characters. I think a good workflow is to set the text in the editor to that width (plus indentation), and then make sure that no code lines go over the limit.
