Interesting, that happens for me too, it does really seem to be a bug in
gnome-terminal.  It doesn't seem to happen if font-locking is turned

Note that what emacs sends to the terminal is _not_ the same as what's
in the buffer, it's a sequence of characters which should make the
terminal render the display Emacs wants to present.

In particular, the terminal redisplay engine can send a TAB character to
move the cursor when it thinks that will be more efficient (in other
circumstances, it might send a sequence of spaces or a cursor-addressing
escape sequence).
