Hi Steve, could you do please commit that? I have run into problems that 
won't work without "|" because I would like to exchange "ref" so simply 
using add won't work and set neither, because I don't know whether the 
combinations of things I want to use do exist.

Best however would be a command to append labels like { append name 
'${ref}' } that would replace the current command
{ name '${name} {ref}' | '${name}' | '${ref}' }. In case that nothing in 
the append name '' exists then it will not be carried out. In case that 
some exist, only those existing should be placed.
