Thanks to you, Peter, & Ray for reviews.   I merged this, and thought
"Okay, time to cut a new release."  And then I found the mistake.

automake automatically includes a file named "README" in the tarball.
It does not include a file named "README.md".

So, we seem to have two choices:

1) Ship with README.md:
	Just add "EXTRA_DIST = README.md" to Makefile.am in every component.
.
2) Ship with README:
    Follow our pattern with Changelog & INSTALL files and add a macro
    to xorg-macros.m4 to define a makefile macro such as:
	README_CMD = cp -f $(top_srcdir)/README.md $(top_srcdir)/README
    and in Makefile.am in every component:

+README:
+	$(README_CMD)
+
-dist-hook: ChangeLog INSTALL
+dist-hook: ChangeLog INSTALL README


Anyone have a preference?   Shipping README.md seems easier - will it cause
problems for any distros or packagers?
