* add some spaces for separation, increasing readability
* do not use the non-existent variable x as replacement, but an actual
empty string ""
* don't use the "truth-y action" at end to make awk print the line ($0)
but explicitly print $0 after the gsub, makes it easier to get for
people with not much awk background
