w.r.t. to my just submitted errata, it appears that its my github ignorance. Shift clicking on the file doesn't have the obvious semantics, but the button on the right side of the pane "download zipfile" does. So my request would be for a slight change to the text to make this clear for us cvs, sccs, svn, bitkeeper folks who didn't get with Git.
Note from the Author or Editor:
Github Readme adjusted to indicate Download Zip button.
