Two commands cannot contain the same named flags

[lucymhdavies]

For example, I have

https://github.com/LMHD/lucli/blob/master/cmd/jess.go#L35-L36

	command.Flags().StringP("image", "i", "jess/firefox", "Image to use")
	command.BindFlags()

In my init function, I have

https://github.com/LMHD/lucli/blob/master/cmd/jess.go#L53

		image := cli.FlagValues().GetString("image")

For this command, the correct value is used (either the default, or user-specified)

$ luclidev jess
INFO[0000] Using image: jess/firefox
INFO[0000] Pulling image layers... please wait           image=jess/firefox

However, if I have another command (in my case named "generic") which uses the same named flag, then cli.FlagValues().GetString("image") returns the default value of the "image" flag from the other command.

As a workaround, I've renamed the flag in the new command:
LMHD/lucli@6c6d63a
