git/log: only count the messages we show when limiting counts

Browse source 
when logging with `git/log -c count', we would count all messages
that we inspected, rather than just the ones that got printed.
This isn't what we should have done.

While we're in here, refactor show() to only show the message,
rather than filtering and then showing.
