Clean up some markup cruft. A number of the macros that take no
...
parameters (like \UNIX) are commonly entered using an empty group to
separate the markup from a following inter-word space; this is not
needed when the next character is punctuation, or the markup is the
last thing in the enclosing group. These cases were marked
inconsistently; the empty group is now *only* used when needed.

Changed all the examples with ugly platform-dependent float output to use

numbers that display nicely after repr(). From much doctest experience
with the same trick, I believe people find examples with simple fractions
easier to understand too: they can usually check the results in their
head, and so feel confident about what they're seeing. Not even I get a
warm feeling from a result that looks like 70330.345024097141 ...
