On `moar --help`, if `moar` is not the default pager, try identifying the user's shell and print instructions for setting `PAGER` in that shell. Identifies fish or Powershell, then falls back on bash / zsh instructions (since I failed to come up with a sensible way of identifying those). Before this change, we always printed bash / zsh instructions. Fixes: https://github.com/walles/moar/issues/251
