It's because of getkeymapcmd():

    if(lastlen != keybuflen) {
	unmetafy(keybuf + lastlen, &keybuflen);		<-- here
	ungetbytes(keybuf+lastlen, keybuflen);
	if(vichgflag)
	    vichgbufptr -= keybuflen;
	keybuf[lastlen] = 0;
    }

Seems like it ought to do the following?  Or else use a temporary instead
of stomping on keybuflen.
