Formatting tweaks for post templates

[mlissner]

These are little things I've seen emerging:

1. The "Now following" post doesn't need line returns between its links because they're cut short anyway. So it should go from:

   Docket: ...

   Complaint: ...

   Context: ...

   To:

   Docket: ...
   Complaint: ...
   Context: ...

   It'll look tidier and save three line returns.

2. On BlueSky, we replicate buttons by doing [ Docket ] | [Complaint] | [Context]. Nobody else is using brackets this way. This can just be Docket | Complaint | Context.

I think that's it for now. Easy stuff next time we're in this part of the code.
