VT100 chops all preceding occurrences of the last character in the last
packet if the last character is ^Z or 0x00; it chops until it encounters a
character that isn't the same as the last char.  I.e.

	if((firstchar = bufr[--bufptr]) == 0 || firstchar == 0x1A)
	    while (bufptr && bufr[--bufptr] == firstchar)
		;
	bufptr++;
	write(fd, bufr, bufptr);

I'll try to remember to make auto-chop an option in the 2.9 version.
