- Conditional compilation (via FEATURE_NCURSES_COLS) to either use
ncurses COLS and LINES global variables, or determine these from
the WINDOW structure.
- .taskrc debug= now defaults to 'off', which will reduce clutter
and won't surprise beta testers.
- interactive.cpp did not compile when ncurses was not detected by
autoconf. That code branch obviously never got executed.
- The interactive shell now instructs the user to type 'quit' to
leave the shell.
- Renamed files task.h -> main.h, task.cpp -> main.cpp. This is to
prepare for the next rename, which addresses the OpenBSD bug.
- Removed utf8.h, utf8.cpp from Makefile.am, which were inadvertantly
added.
