In which case I know how to fix this:

(x@h)30> xref:start(foo, {xref_mode, modules}).
{ok,<0.7716.0>}
(x@h)31> xref:set_default(foo, builtins, true).
{ok,false}
(x@h)32> xref:add_release(foo, code:lib_dir(), {name, otp}).
{ok,otp}
(x@h)39> xref:q(foo, '(X+B) * math:_/_').
{ok,[{math,exp,1},{math,log,1},{math,pi,0},{math,pow,2},{math,sqrt,1}]}
(x@h)40> xref:q(foo, '(X+B) * erlang:"is_.*"/_').
{ok,[{erlang,is_alive,0},
      {erlang,is_atom,1},
      {erlang,is_binary,1},
      {erlang,is_boolean,1},
      {erlang,is_builtin,3},
      {erlang,is_constant,1},
      {erlang,is_float,1},
      {erlang,is_function,1},
      {erlang,is_function,2},
      {erlang,is_integer,1},
      {erlang,is_list,1},
      {erlang,is_number,1},
      {erlang,is_pid,1},
      {erlang,is_process_alive,1},
      {erlang,is_reference,1},
      {erlang,is_tuple,1}]}


(except distel's completion currently isn't using xref, but it should)
