Currently, in the elliptic-curves codebase, there are quite a few occurrences of the following formatting quirks:

• Lines indented by 4n-1 instead of 4n spaces.
• Non-standard use of - and -- in input/output lists.
• Lowercase .. note:: or .. warning:: blocks, and occasional use of AUTHOR: instead of AUTHORS:.
• Excessive empty lines.

This patch makes an attempt at cleaning up these things somewhat.
