Previously you would use prev and next to round the corners of the
items in the pagination list. I changed it to use the first-child
and 'last-child' becuase you want the corners rounded regardless of
whether or not you have a list item marked with the prev or next
class. For example, I have the following pagination list:
[1][...][12][13][14][15][16][...][23]
I could have added the prev and next classes to the boundary
items (1 and 23), however it's semantically incorrect, and I think
this solution is more flexible.
