Subject: [PATCH] fish: functions: Make it easier to review code with difftool
 aliases

If no arguments are provided to the git difftool aliases, just invoke
it with the default `git difftool main...current-branch`. This is what
we will use most of the time anyway as this is exactly the command
needed when we want to review our own changes before pushing upstream
or reviewing some other merge request.
