	For the apple platform, search the Library directory
	Apple likes its applications to use:
	    /User/Me/Library/Application Support/
	directories, so we do if __apple__ is defined

	Files modified::
	* src/cfg-file.c: define MAXPATHLEN and MAX_CFG_NAME_SIZE
	  (check_home_dir): new -- look for a ".local" directory to extend

	  the directory name in a buffer large enough to append the config
	  file name.
	  (find_apple_cfg_dir): If __apple__ is defined
	  (set_cfg_dir): parse out its functionality into the above procs

	* src/cfg-file.c: Likewise, but also add two additional home dirs:
	  XDG_DATA_HOME and XDG_CONFIG_HOME (if present in the env).
	  This gets replicated in sort-pw-cfg.c as well.
	* src/domains.c: The domain list file code is moved to here
	* src/fwd-preamble.txt: static text for the "fwd.h" header
	* src/gnu-pw-mgr.c: Remove domain list file code to domains.c
	* src/opts.def: Remove export text to fwd-preamble.txt
	  clean up some documentation for --cclass and --rehash

	Obsolete the varying confirmation answer
	The original version varied whenever the password changed.
	That is undesireable behavior. So for a number of years,
	both the old and new methods were produced. The old method
	has now been relagated to a new, but deprecated, option:
	--old-confirm, with no single letter equivalent.

	Files modified:
	* src/opts.def: add some globals to reduce having to re-build marker strings
	   Make the --confirm option settable, add a deprecated
	  --old-confirm option and have that option set --confirm.
	* src/pw-opts.c: Break up how getting and setting stored options are handled.
	* src/seed.c: (set_default_cclass): use globals instead of rebuilding marker
	  and reacquiring the config file text.
	* src/gnu-pw-mgr.c: Alter set_confirm_value() to only do one or the other,
	  depending on whether HAVE_OPT(OLD_CONFIRM) is true.
	* tests/base.test: adapt the testing and make it more debuggable.

	add a 3 characters in sequence password fix
	Chase Bank has added the password restriction that no three characters
	may be in sequence. So look for that and fix it, if need be.

	Let people know when they last modified a password.
	Mark the day when the pbkdf2 count is modified.

	The confirmation value printed out is a hash based on the confirmation
	string and the current password. So, if the password changes, then
	so does the confirmation string. Not ideal. This change restricts
	the hashing source to just the password id and the confirmation
	string.

	keep track of domains
	When the number of passwords approaches many tens of logins,
	it becomes unwieldy to track which domains have passwords.
	With the new --domain option, this program will keep track
	of a domain name and a last accessed date.  The saved
	domain name should not reveal the domain transform.  If
	you do, then you have effectively stored the password id
	in plain text.  Not a good idea.

	Answer security questions
	Extract from the new option definition:

	Some web sites use "confirmation questions" that, supposedly, only
	you know the answer to.  Unfortunately, these are often times
	questions that can be researched by others or they can be questions
	that you have forgotten the answers to or may have multiple answers
	for.  The net result is that you are locked out.  This option makes
	it easy to get consistent answers to these questions and have these
	answers be different for every web site, just like your password.

	Providing this option will cause the argument to be merged into the
	hash source (changing the resulting password).  Exactly 12 letters
	will be extracted from the hash and converted to lower case.  The
	string argument to this option should be the last word or two from
	the question, yielding an easy-to-remember way of obtaining a
	consistent answer to these inscrutable questions.

	You will need to update your confirmation question answers when
	you update your password seed.

	Only use cruft fixup code for older seeds
	and mark newer seeds with a version stamp

	* src/fix-pw.c (fix_std_pw): check for a version
	* src/gnu-pw-mgr.c (print_pwid): set the seed version,
	  defaulting to zero if not present, then call the fixup
	* src/seed.c (add_seed): include the current prog version

	specify unchanged vars as "static"

	require two chars of one class
	I bumped into a site that required two lower case letters
	in the password.  So, now allow specifying at least two
	uppers, lowers, digits or special (punctuation) chars.

	* src/cclass.c (adjust_pin_n_alnum): if any of the two-whatevers got set,
	  ensure that the CCLASS_WHATEVER bit is set.
	* src/fix-pw.c (ck_pw_classes): basically rewrite the thing.  Instead of
	  a pointer to the second occurrance of things, instead manage a count
	  of characters of a particular class.
	  (pick_something): a function to handle special (punctuation) characters
	  when they are disallowed.  Called from ck_pw_classes().
	  (fix_std_pw): also rewritten.  Do a check of each of the required
	  classification bits and call an "add_something" function to fix issues.
	  (add_upper): new
	  (add_lower): likewise
	  (add_digit): likewise
	  (add_special): likewise
	  (find_upper): new to support the add_xxx functions
	  (find_lower): likewise
	  (find_digit): likewise
	  (find_special): likewise
	* src/opts.def: define two-upper, two-lower, two-digit and two-special
	* tests/base.test: test that this works.

	show password id status
	* announce.txt: new file for making announcement
	* src/gnu-pw-mgr.c (print_pwid_status): do the display
	  (print_pwid): call that function when --status is specified
	* src/opts.def: add the option
