Reduce test terminal size from 80x24 to 60x15

Browse Source 
Smaller virtual terminal fits better in normal-sized terminal windows
for users running the test suite.

Updates affected tests:
- test_horizontal_scroll: adjust char counts and cursor positions
- test_multiline_wrap: adjust char counts for 60-col wrapping
- test_multiline_cursor_movement: adjust char counts
- test_multiline_history: adjust char counts
