When I copy and paste your buffer names, the issue seems to be that
`string-width' returns an incorrect value (eg 13 when the buffer name
actually seems to occupy 12). Although some of these characters seem
to have a non-integer width on my system, so I don't see that it is
possible to get this right. But it still looks more wrong than it
should be (off by > 1 character).
