The format _strings_ were previously centralised into the platform-
independent console.c, as const char arrays. Now the actual formatting
operation is centralised as well, by means of console.c providing a
function that takes all the necessary parameters and returns a
formatted piece of text for the console.
Mostly this is so that I can add extra parameters to the message with
some confidence: changing a format string in one file and two fprintf
statements in other files to match seems like the kind of situation
you wish you hadn't got into in the first place :-)
