Make hybrid bindings easier to achieve

Browse Source 
The vi-bindings function would unconditionally erase all bindings,
making it impossible to call it last. This would disable the
mode-indicator (and in future also the cursor).

Make it so any argument to fish_vi_key_bindings stops it from erasing
bindings.

It would also be possible to demand an argument to erase (or to erase as
a separate step). but the usual case seems to be _switching_ to a set of bindings.

Vi mode allows for the use of Vi-like commands at the prompt. Initially, <a href="#vi-mode-insert">insert mode</a> is active. @key{Escape} enters <a href="#vi-mode-command">command mode</a>. The commands available in command, insert and visual mode are described below. Vi mode shares <a href="#shared-binds">some bindings</a> with <a href="#emacs-mode">Emacs mode</a>.
It is also possible to add all emacs-mode bindings to vi-mode by using something like
\fish
function fish_user_key_bindings
# Execute this once per mode that emacs bindings should be used in
fish_default_key_bindings -M insert
# Without an argument, fish_vi_key_bindings will default to
# resetting all bindings.
# The argument specifies the initial mode (insert, "default" or visual).
fish_vi_key_bindings insert
end
\endfish
When in vi-mode, the <a href="fish_mode_prompt.html">`fish_mode_prompt`</a> function will display a mode indicator to the left of the prompt. The `fish_vi_cursor` function is available to change the cursor's shape depending on the mode in supported terminals.
