Having submodules causes vim-plug or other vim plugin managers to clone
them with no real benefit to the end-users. There's currently no
compelling reason for me to use submodules.

zsh: fzf-completion: use noshwordsplit local option

This also fixes the completion causing a bell / flickering in case
"shwordsplit" was not set, because then the function would return false.

[bash-completion] Add nvim to f_cmds

Not relying on exit status for CTRL-R

Patch submitted by @robinro and @JackDanger
Close #403 #242 #241 #203

In the case that fzf-tmux returns a user-selected result but with a
non-zero exit status (which can happen if a function inside $PS1 returns
non-zero) this allows CTRL-R to continue working as expected.

Addresses #203 (Tranquility's comment)

This prevents fzf from missing SIGWINCH during startup which
occasionally happens with fzf-tmux

Close #400
