Code review comment for lp:~bladernr/checkbox/1153894-clarify-mediacard-instructions

this stupid commit message stuff in git is confusing... I apparently squashed the wrong thing but the messages DO reflect the changes done.

Anyway, fixed the output, had to redo the whole branch because I messed it all up trying to rebase on the latest trunk which caused git to delete all my changes :( I finally just gave up and redid it from scratch.
