cleanup winner README.md files
Fixed cases where there was a bad trailing backslash. Improved a few cases where a code block was needed to highlight some text. Changed a few cases where a code block needed to declared as, say, a sh code block. Fixed a few cases where the winner information was not properly formatted. Plus a few nits and clarifying text was added.

So, node 0 has edges to / depends on nodes 4 and 8, node 1 depends on
|

node 0, and so on. Then, it groups the graph's nodes into

strongly connected components and prints them in reverse-topologically

sorted order:

`-Wno-missing-prototypes` is necessary because there aren't any
