+ + in-progress changes to provide an extended version of putwin and
+ getwin which will be capable of reading screen-dumps between the
+ wide/normal ncurses configurations. These are text files, except
+ for a magic code at the beginning:
+ 0 string \210\210 Screen-dump (ncurses)
+
+20150307
+ + document limitations of getwin in manual page (prompted by discussion
+ with John S Urban).
+ + extend test/savescreen.c to demonstrate that color pair values
+ and graphic characters can be restored using getwin.
+
+20150228
+ + modify win_driver.c to eliminate the constructor, to make it more
+ usable in an application which may/may not need the console window
+ (report by Grady Martin).
