[PATCH 06/20] announce.html.in: Clarify.

[G. Branden Robinson]

As I read X/Open Curses Issue 4, Version 2, and Issue 7, there is no
requirement "that every macro entry point has a corresponding function".

What the standard says is: "[a]ny function declared in a header may also
be implemented as a macro defined in the header".

These are not equivalent statements because there can be macros that the
standard prescribes as such, and this is in fact the case with the
function-like macros in man/getyx.3x.
