Summary: (At least my build of) PHP tries to do readline magic on the terminal
when invoked from the shell, even inside bash's command substitution operator.
Work around it by piping the output of ##echo## to ##php##, so the input isn't a
terminal.
Test Plan: ##bash$ arc li<TAB>## now gives me possible completions rather than
breaking and inserting a literal tab
