complete/fish: Take RIPGREP_CONFIG_PATH into account

Browse Source 
The fish completions now also pay attention to the configuration file
to determine whether to suggest negation options and not just to the
current command line.

This doesn't cover all edge cases. For example the config file is
cached, and so changes may not take effect until the next shell
session. But the cases it doesn't cover are hopefully very rare.

Closes #2708
