I've tagged a place where we're printing a lot of characters in a loop and putting in a linebreak between the characters will make logs a lot less useful :)

As a separate effort, there are likely a bunch of these log statements that can be disabled for normal use.

I've reviewed a dozen files in the code that are ones I'm familar with and this looks flawless.
