Yeah. I definitely flip-flopped on this when preparing this for the
list. I still feel like 'uploadpackfilter' is gross, so I was hoping to
send it with 'uploadpack.filter' (which reads nicely, but forces us to
write some gross code), but both options are frustrating to me for
different reasons.
Playing around with it more, though, I think that uploadpackfilter is
our best bet. I'd hate to introduce a string manipulation bug by munging
the reuslt of 'parse_config_key()', which is so clearly designed for
something like 'uploadpackfilter[.<filter>].allow'.

I dropped the case-insensitive matching in the latest revision. I don't
think that we need to be overly accommodating here.
