2015-02-28  Sam Varshavchik  <mrsam@courier-mta.com>

	* Update to courier-unicode 1.2.

2013-02-20  Sam Varshavchik  <mrsam@courier-mta.com>

	libidn go off the rails.

2011-02-12  Sam Varshavchik  <mrsam@courier-mta.com>

	* rfc2047.c (do_encode_words_method): Avoid splitting RFC 2047-encoded

2011-02-10  Sam Varshavchik  <mrsam@courier-mta.com>

	* rfc2047.c (rfc2047_encode_callback): Likely bug fixed.
	(rfc2047_encode_str): Ignore invalid charset sequence when encoding

	* rfc822/rfc2047.c (rfc2047_encode_callback): Rewrite broken logic.

2011-01-22  Sam Varshavchik  <mrsam@courier-mta.com>

	* rfc822/encodeautodetect.c (libmail_encode_autodetect): Remove obsolete
	unicode API. Determine encoding with heuristics based entirely on
	the content. Remove charset arg, replace with "use7bit", to force
	qp or base64, instead of 8bit. Take a binaryflag param that gets set
	to indicate whether base64 was selected based on binary content.

	* rfc2047.c (rfc2047_encode_str): Removed
	rfc2047_encode_callback_base64, invoked from rfc2047_encode_str().

2009-11-21  Sam Varshavchik  <mrsam@courier-mta.com>

	* rfc822_getaddr.c: Remove rfc822_prname() and rfc822_prname_orlist(),
	replaced by rfc822_display_name() with a NULL character set.

	* rfc2047u.c (rfc822_display_name): Semantical change -- without
	an explicit name, display the address as the name. If the requested
	character set is NULL, do not decode RFC2047-encoded content, return
	it as is.

	* rfc2047u.c (rfc2047_print_unicodeaddr): Fix several formatting

	character.

	(rfc2047_print_unicodeaddr): Do not output a dummy name for an
	address without one.
	(rfc822_display_addr_str_tobuf): New function, version of

* Yes, I've decided to start a Change Log. librfc822 now has a life of its
own, so it might as well have it.

* Courier needs tokens in a link list, not an array.  Rewrote most token
handling code.

* Fixed some issues with handling of () comments.

* Changed *pr* functions to pass along a caller-provided void, also for
  courier.  librfc822 should now be threadable (like, who cares...)

* Added a testsuite
