read-command doesn't explicitly handle multibyte characters in the way
self-insert does.  self-insert gets the remainder of the character.
That doesn't work for you because you want KEYS to be correct before the
self-insert.  KEYS refers to the level where you originally read the
keys, in getkeybuf() / getkeymapcmd(), and at this point you've only got
the initial byte.

So I'm not sure what the fix is.  I think it might be (despite what the
comment in getkeymapcmd() currently says) to move the special stuff down
to the end of getkeymapcmd() and posprocess it into keybuf, which isn't
very nice but, well.  I'll look later on.

Can't really see a good reason for not producing a bug fix version anyway,
though, since there's plenty of stuff needs fixing.
