There are currently six variations of each conditionals, and there may
be more in the future (e.g. %while). Stop trying to enumerate them all
everywhere.
Add support for index copying in the document processor.
Have pptok.pl auto-generate index metadata for conditional
preprocessor directives.

Along with C and other languages, the current trend is to be able to
probe for features rather than relying on version numbers. This is
motivated in part by the intent of bumping the major version number to

Add the %null(), %note(), %warning(), %error(), and %fatal()

allow %ifdef to test for them instead of coming up with something
entirely new.

Link from %if to %is(), not just the other way.
Clarify that %is() is valid everywhere, not just in an %if expression
(unlike defined() in C.)

The %unimacro directive is almost a footnote, but it is really
important to use the correct directive. Put it on equal footing with
%unmacro.
