Log: terminal.fs: fix handling of NULL (0x0) control code
NULL is defined as a no-op, so make sure that we detect it and exit (term-emit) immediately. Otherwise we fall through to the default code which redraws the character and advances the column by 1.
This fixes the staggered line output that appear in quik.
