Remove lower-level posts' right padding

I have no idea why the padding was there. It definitely shouldn't
be at the right hand side (which pushed the ... menu and the
timestamp inward)

If the padding is still needed on the left hand side (not sure why,
but I may have missed something), this should be changed to:
    padding: 0 0 0 .5em;

Also removed the border-left thingy. There is no left border &
removing it doesn't seem to change anything.
