Move the completion function to the autocomplete script.
Fix some issues with cursor shape setting, respect user configuration.
Functions and vars start with two underscores, following the convention.
Other minor refactoring.
Less intrusive (in some ways) than adding symlinks to ~/.config/fish
Exploits the fact that fish loads scripts from XDG_DATA_DIRS on startup.
Thanks to @page-down for noticing
