Done -- almost all as suggested, and a couple of others that I saw while
editing.  All the multiline changes in the attached patch are due to
refilling.  I notice, however, that some of the text is inconsistent and
confusing, particularly in the Composite Sexp Widgets node; the
descriptions of the composite widgets are not parallel in style and
elements of the value of a set widget are said to be irrelevant when
surely it is their order that is irrelevant.  I don't know enough about
the widgets library to reliably fix those (I may even be incorrect about
their incorrectness), so I'm just drawing attention to them.
