I installed arc on a windows box. Installing php and cloning the repositories worked fine. Also arc runs fine. However arc tries to output escape sequences for coloring its output which for some reason does not work correctly:
$ arc help ←[1mNAME←[m ←[1marc←[m - arcanist, a code review and revision management utility ←[1mSYNOPSIS←[m ←[1marc←[m ←[4mcommand←[m [←[4moptions←[m] [←[4margs←[m] This help file provides a detailed command reference. [...]
Colors work fine for my git bash prompt. Colors work also fine when doing arc help|cat. - I'm not sure what is going on there.
