dash (Debian's /bin/sh) doesn't support echo's -e flag: it prints "-e"
literally as text before processing the rest of the string's backslash
escapes. Every script's colored banner was affected. printf's escape
handling is POSIX-mandated and behaves identically under dash and bash,
so swap all 90 echo -e calls for printf, appending the trailing \n that
echo used to add implicitly.
