this is not yet supported:
..X => rust-lang#37854 is still open

* Adjusting log line in `fuchsia-test-runner.py` to refer to self

This is common syntax used for intra-doc links, so fixing it should help
with doc formatting.

* Merge the color-changing block into the regular rules, which was
  probably written that way because it used to be in the theme files,
  but has no reason to be written this way now that it's in rustdoc.css

* Get rid of redundant `display: block`, since `position: absolute`
  blockifies the layout anyway.

Minor grammar nit.

Remove ..X from RELEASES.md
