Support binding search functions to Ctrl+Space using bind -k

[daxzel]

Curently fzf_configure_bindings doesn't support "bind -k" format which doesn't allow to configure ctrl+space binding as it is only can be set using -k syntax see fish-shell/fish-shell#3189 (comment)

Hi Daxzel, is the specific issue that you want to use Ctrl+Space to activate a fzf.fish search command but that isn't currently supported?

[PatrickF1]

Oh I see, so Ctrl+space generates the null character, and is the only key binding that needs to be binded using bind -K, not by normal bind. Did I understand your problem correctly?

[daxzel]

Yes, that exactly correct. While I solved my problem by looking into the script and setting a bind manually it still could be confusing for others.

Gotcha. It'd be a sizable refactor to update it for not much additional functionality/flexibility, in my eyes. However, I will update the troubleshooting to call it out. Thanks!
