+ modify makefile rule to make the ".png" filenames created by groff
predictable.
+ add option --help-tags to allow scripts to get the item's tag field
consistently from help- and help-item button results rather than
getting the item's text for the latter (discussion with Florent
Rougon).
+ correct manpage discussion of DIALOG_ITEM_HELP versus --item-help,
as well as --help-button return status (report by Florent Rougon).
+ correct limit used for --hline option (report by Devin Teske,
cf: 2011/06/30).
+ do not print empty "[]" if a --hline option was given with an empty
value (report by Devin Teske).
+ miscellaneous configure script fixes/updates. In particular, add
option --with-shared which builds shared libraries without a libtool
dependency.
+ add FreeBSD port-files for test-builds.
+ update lt.po, add fa.po from
http://translationproject.org/latest/dialog/
+ update config.guess, config.sub
