Maybe we should add a check for the terminal size for v.digit.
At least a warning in the man page would be appropriate.

This I tried, but I didn't understand how to do it (curses
didn't give me the numbers as suggested by Glynn). An expert
is needed here

It works fine for me. If I add the line:
fprintf(stderr, "LINES = %d, COLS = %d\n", LINES, COLS);
to Init_curses() in dig_curses.c, it prints:
LINES = 24, COLS = 80
Note that v.digit doesn't initialise curses until after you have
selected a digitiser, selected a map, and filled in the information
screen for the map.
The variables are set by curses and, as such, aren't valid until
curses has been initialised (by initscr(), which is called from
V_init()).

Ah! This is the point. I added the test too early.
The variables are set by curses and, as such, aren't valid until
curses has been initialised (by initscr(), which is called from
V_init()).
However, it will be also strange that v.digit stops working in the middle.
To have the test at the very beginning might be more conventient.
But of course: later is better than nothing.
