fish shell support

[Globegitter]

It would be great to get https://github.com/fish-shell/fish-shell/ support. Currently getting these errors:

Hello @Globegitter. I'll install fish-shell and tinker with it.

This file is valid for ZSH or bash, but it isn't going to work with fish.

@Globegitter: Do you mind trying this out and see if it helps? https://github.com/edc/bass

Here's my working solution:

$ cat config/fish/functions/pair.fish                                                            
function pair --description "begin pairing"
hitch  $argv[1] $argv[2]
source ~/.hitch_export_authors
end

$ cat config/fish/functions/unpair.fish                                                                
function unpair --description "end pairing"
hitch -u
set -e GIT_AUTHOR_NAME
set -e GIT_AUTHOR_EMAIL
rm ~/.hitch_export_authors
end

and in config.fish:

if test -f ~/.hitch_export_authors; source ~/.hitch_export_authors; end
