fish shell completion

[leoetlino]

Would you consider adding support for fish shell completion?

It is much less painful than writing files for other shells, but I couldn't figure out how to port the current completion scripts.

Here is a link to the fish docs: http://fishshell.com/docs/current/commands.html#complete

I'd take a patch for this, but I won't be adding this myself.

I'd like to understand how fish completion works I'm going to read the docs and take a stab at this

I guess this has to be submitted upstream instead: https://github.com/fish-shell/fish-shell/issues?q=is%3Aopen+is%3Aissue+label%3Acompletions
