Could you instead use \endash<tab> to replace the minus sign in lists:

@doc """
       – 1st line\\\n
       – 2nd line\\\n
       – 3rd line
       """ z = 7

Result in the REPL:

help?> z
search: z zip zero zeros ZeroPivotException set_zero_subnormals get_zero_subnormals count_zeros    

  – 1st line
  – 2nd line
  – 3rd line
