I think the reason completion is not working is because of this line
in share/completions/git.fish:
function __fish_git_using_command
...
# aliased command
set -l aliased (command git config --get "alias.$cmd[2]" ^
/dev/null | sed 's/ .*$//')
...
So this is basically looking for aliases created via git itself ('git
config alias.gco checkout' etc).
To fix your issue, you either need to define an alias with git, or
modify the __fish_git_using_command function to check if the given
command is a shell alias and return 0.
