fix usage template conditional

I wrote https://github.com/eparis/readable-golang-template which
converts golang templates into something structured around the
conditionals.  Obviously you can't just USE the output, but you can SEE
the problems.  In this case the output shows something like:

{{if .HasParent}}
        {{if and (gt .Commands 0) (gt .Parent.Commands 1) }}
                Additional help topics:
                {{if gt .Commands 0 }}
                        {{range .Commands}}
                                {{if not .Runnable}}
                                        {{rpad .CommandPath .CommandPathPadding}} {{.Short}}
                                {{end}}
                        {{end}}
                {{end}}
                {{if gt .Parent.Commands 1 }}
                        {{range .Parent.Commands}}
                                {{if .Runnable}}
                                        {{if not (eq .Name $cmd.Name) }}
                                        {{end}}
                                        {{rpad .CommandPath .CommandPathPadding}} {{.Short}}
                                {{end}}
                        {{end}}
                {{end}}
        {{end}}
{{end}}

We have a completely unused "{{if not (eq .Name $cmd.Name) }}"

Move the {{end}} after the {{rpad...}}
