Just poking you because of it through bugzilla as you're sleeping now. Needs fixing for sure, some people around are even taking example of them and cloning to new docs.
Please fix other articles as well - mine too (slap slap slap). :s/ctrl+v<TAB>/<two spaces>/g10000 is enough ;]
Fixed 1, 2 and 3 and bash part 1 as well. Rest seem fine.
