Merge pull request #5 from mwichmann/master

reach in and grab Mats README.md
get rid of horiz scroll boxes on the long ENUM
more 80 col chauvinism
try to add an interal link to and return from a endnote
and add a needed linebreak before that nav element (perhaps)
missed a # anchor
the return needs to preserve context, so put it ABOVE the reading point
more readme fiddling
