Rebased. Are we good to go now, @teto @khaneliman?

Just not a fan of this option set in the current form. It is too verbose and maintenance heavy to keep adding a new option for each possible setopt and unsetopt. We currently have setOptions available to do the same thing.

Seems more like we should deprecate these options and encourage usage of that setOptions option? Or is this something that needs to be set in a specific location in the file?

I agree that this is verbose. I wasn't aware of setOptions. Should be sufficient!

Personally, my favorite form would be something like:

setOptions = 
          lib.mapAttrsToList (name: enabled: if enabled then name else "NO_${name}") {
            APPEND_HISTORY = false;
            EXTENDED_HISTORY = true;
            HIST_EXPIRE_DUPS_FIRST = false;
            HIST_FCNTL_LOCK = true;
            HIST_FIND_NO_DUPS = false;
            HIST_IGNORE_ALL_DUPS = false;
            HIST_IGNORE_DUPS = true;
            HIST_IGNORE_SPACE = true;
            HIST_SAVE_NO_DUPS = false;
            INC_APPEND_HISTORY = true;
            SHARE_HISTORY = false;
          };

This helps to keep alphabetical sorting. But the current setOptions is also fine.
