Making commands explain why they are failing.

Also, I figured out why my earlier "simpler" workflows for cloning
gh-pages were failing: I had misspelled gh-pages as "gh-pqges" in the
cloning command.
Attempt to fix format of command.
Okay I think this is the right format now, so use it in both places.
Now trying to clean up the make output a little.  This may be misguided.
Commit final test.
