* generate_dist_headers.sh: Use a heredoc instead of multiple
	echoes.
	Do not add mln/version.hh (leave it to Makefile.am).
	Echo status messages on stderr, not stdout.
	Use a single `find' to search `*.hh' and `*.hxx' files.
	Remove the useless post-processing pass dropping Subversion's
	cached copies, as they are not caught by find anyway.
	Sort results before performing string replacement.
	* Makefile.am (nobase_include_HEADERS): Add mln/version.hh.
