Subject: [PATCH] Add P_CENTER mode flag for printing centered multline text
buffers/strings
When used with putmsg(), centers the output based on the longest line.
When used with printfile() line at a time mode, centers each line.
When used with printfile() open/close mode, centers just the first line.
So it's a little weird and wonky.
