Cosmetic tweak.
Add -zZ support to grep (NUL delimited input/output).
Link to a couple more things from nav bar.
A few more commands in request section of roadmap.
The README trailed off into unfinished confusion at the end, fix up the obvious parts.
Add new paragraphs on trading off different _kinds_ of simplicity (easy for machine to run vs easy for humans to follow), and why comments aren't a substitute for good code.
More work on the cleanup page, partway through describing ifconfig.
