single-quoted. Remove some redundant quotes around code. Clarify
meaning of `iff' further for those that didn't get it the first time
'round (like me). Make graphical indicators samples, not code. Put
results of evaluation on the same line as @result symbols. Use @print
example as example of total usage, and remind readers not to forget
the difference.
paragraph format (somewhat clumsy-looking on paper, at least) to
@table format, with headers @strong. Made example modules complete
sentences. From Stephen Compall, thanks!
