i'm catching up on a month's worth of mail (which accumulated during
my vacation).

>> a {
>>  background-position: 0 0;
>> }
>> a:hover {
>>  background-position: unchanged -50px;
>> }
>> a:visited {
>>  background-position: unchanged -100px;
>> }

personally, i'd want "inherit" instead of "unchanged" since "inherit"
exists in css today.
(this isn't an endorsement for the proposal.)
