Now ncurses-based programs such as sysinstall and mc will display the
correct font for graphical lines instead of "-" and "+" characters.
Correct two special characters for cons25l1 in termcap: use real
arrows instead of ">>" and "<<".
Add a lot of additional symbols for line drawing which are taken from
the CP437 font.
Almost all of the ACS symbols are now implemented.
