[arm/master] Option for disabling ACS support
by atagar＠torproject.org 30 Nov '11

commit b96f129b9349ccfb53d5eeb9c54b4c063fce3804 Author: Damian Johnson <atagar(a)torproject.org> Date: Wed Nov 30 10:13:55 2011 -0800 Option for disabling ACS support Some terminals have issues with alternate character support which is widely used by arm for borders. Unfortunatley this makes the interface look pretty crappy... http://www.atagar.com/arm/images/acs_display_failure.png Explaining the issue in the README and adding an option to manually remedy the most obvious broken bits. ACS is used throughout arm so it's gonna take a much more invasive change to allow the user to completely replace ACS usage (for instance, we can't use the curses box() function...).
