Btw., it seems to be a bug in ncurses. ee correctly checks for an
error return from wgetch() (albeit using -1, as opposed to the opaque
macro ERR), but wgetch() is returning 0.
(gdb) step
Single stepping until exit from function wrefresh,
which has no line number information.
main (argc=2, argv=0xefbfd7e4) at /usr/src/usr.bin/ee/ee.c:608
608 in = wgetch(text_win);
(gdb)
609 if (in == -1)
(gdb) print in
$2 = 0
(gdb) list
604
605 while(edit)
606 {
607 wrefresh(text_win);
608 in = wgetch(text_win);
609 if (in == -1)
610 exit(0);
611
612 resize_check();
