You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: commands.go
    path of file: ./repos/teller/vendor/github.com/gopasspw/gopass/internal/backend/storage/gitfs
    
    the code of the file until where you have to start completion: package gitfs

import (
	"os"
	"os/exec"
	"strings"

	"github.com/gopasspw/gopass/internal/action/exit"
	"github.com/gopasspw/gopass/internal/out"
	"github.com/gopasspw/gopass/pkg/ctxutil"
	"github.com/urfave/cli/v2"
)

// Commands returns the commands that are available for the gitfs backend.
// TODO: maybe we just want to add the Before action when populating the final
// command slice (unless it's non-nil so backends can override it). A similar
// approach could be taken with the Action function. We could wrap it, parse
// "global" flags like store and put that into the context. A bit hacky
// but on the other hand less ugly wrt. the function signature.
