Fixes in 1986, manifest update

The html files in 1986 (including 1986/marshall/compilers.html) look and
feel good. Format change (slight) in 1986/marshall/index.html.

The manifest update includes a fix for 1986/hague and this same change
in entry_text applies to files in a few other years as well.
