Details:

I omitted a `EE` call in one man page recently, and this caused the font
family to get stuck in Courier until another `EE` call was eventually
encountered, more than one document later.

This led to ordinary body text being set in Courier.

That is not desirable.

The font family should be reset periodically.  I don't think paragraphing
macros are a good place to do it, because one may need an extended example
with multiple paragraphs.

I nominate the (sub)sectioning macros.  An example in a well-formed man page
will not cross a (sub)section boundary.

While I'm there, I'll parameterize the body and example families, but not yet
expose strings for them.
