On Gnome Shell on Wayland `wl-copy` is automatically detected but using
it requires switching focus to the temporary invisible window it creates
as a workaround to the Wayland security feature that only the focused
application can interact with the clipboard. This does not happen when
`nvim` is run outside of `tmux`, so I can only assume that `tmux` is
seen to be the focused application, even though it's running inside
`kitty`, rather than `nvim` when running inside `tmux`.
Some terminals use more characters than others for to display certain
unicode code points, this resulted the statusline to "leak" past the end
of the line causing characters at the next line to be highlighted
incorrectly.
Also move away from using the telescope builtin grep for word under
cursor mapping by extending the `:Rg` command to work in the following
circumstances:
* `:Rg text to search for`
* `:Rg` word under cursor
* `'<,'>Rg` visual selection
